I’m Back

Hi everyone I’m back.  It’s so nice to be back.   I missed all of you really bad.  I will be  posting every week to catch up on my messes.

My nurse still is not coming any more, but my husband makes sure that I take a bath one or two times a week.  It is great.

My husband is a great guy, but he can be annoying sometime but I still Love him.  I still go to Bingo.  I just go, but don’t talk to anyone.  I still go to church, everything is the same.

I went on a weekend trip with the ladies at my church to the mountains.  We had a nice time and everyone spoke about things and I spoke and soon as I started to speak, I cried.  But I kept talking and after awhile I stopped crying and keep on talking.  Everyone clapped and praised me because even thoughI spoke and cried, I stopped on my own.  I felt so thankful.  I didn’t cry no more for the weekend.

I desparately need donations, please give.  All you need to do is pick the donation tab on the left side on the top.



My baths

I am home alone most days, because my husband go to work. I finally got a nurse to come two days a week so that I can take my baths. Even though I can take a bath when my husband come home its that I don’t remember when he is home. Because after we eat dinner it is about 7:00 p.m. Then I watch some television or I’m messing around on the computer then its time for bed and therefore I didn’t remember to tell him I need to take a bath. This is everyday I don’t remember. My sister sent me some sticky’s and I put them somewhere, where I don’t know. The nurse comes on Mondays and Fridays and immediately I jump right to it, because I’ll forget so I do it right then and there. It’s only until March and then thats it, but then my husband knows and he’ll tell me to take a bath and I won’t have to worry about it any more. My husband goes from 7:00 in the morning until 4:30 in the evening. I take him and pick him up. All day everyday all I do is sit home alone. My family is not here its only me.


M y weekend trip

I went on a trip to Tybee Island, Geogia. Me and 22 other girls from my church. It was fantastic.

First, we got there on Friday and left on Sunday. When we left to go I was riding in a black explorer and just before we got there the truck broke down on the side of the rode. We called around for a rental and a tow truck. The rental was too much money. We were gonna wait for the tow truck and there were two other cars with girls and one girl stayed with the truck and I went in one of the other cars to the place we were gonna be staying. After a while they got there with the truck.

Then we were to pick where we wanted to sleep and I picked a room on the first floor with two beds in the room. Later on another car came in and they picked their room. They picked my room and one picked the bed and the two others put their beds on the floor so that meant that there were gonna be four people in my room. It was a big house with plenty of room for everyone. I didn’t cry once.

So when everyone got there and picked where they were gonna sleep and the three girls that was in my room decided they wanted to sleep outside so they moved.

That night all 22 girls were there and we sat around the table and we talked and it was time for dinner. We ate everything we could. It was so very nice and since nobody did not have a conversation with me I didn’t cry at all. It was very nice and enjoyable.

The next day we had breakfast and we talked some more and then someone asked me a question and there it was I cried and then I tried to talk and then I talked with no more crying but I could not remember everyones name. I apologized and it was a good.

Some of the girls went to Savannah to go shopping and I stayed at the house. I went with the girl who truck had broke down. When she tried to start it up, it worked, so me and her and one more person decided to go a store and let them check it out.

We left and we were only a few blocks from the house when it broke down again. We called back to the house for someone to come and pick us up. So when the girl came she asked her to drive down the road to a garage so she can see how much they charge to pick it up and fix it. They picked it up and they were looking to see what was wrong with it.

The girls came back from shopping and we ate lunch. Later on we were sitting and talking and then we took some pictures. I didn’t cry one time on Saturday and I was talking and smiling and everything. Boy did I have a nice weekend. It was great. I remembered everyone’s name.

I thanked everybody for putting up with my crying, what little I did.


My weekend trip

I went away for a weekend trip to a lake in South Carolina. I went with my sisters from Bible Study. It was great. We stayed at one of their lake houses. Everybody cooked something but I didn’t have to cook. We got there on a Friday and left on Sunday afternoon. I had went there and I had to take a needle in my stomach every night and one of the girls gave it to me. I thank her for doing that. But it was joyous and very religious. We read and answered questions about the bible but I cried. They let me cry and went on with what ever we were studing. It was a great weekend trip.


My neice came to visit me

My neice came down from Maryland and I remembered her from before I had my stroke. I kissed her because I loved her very much and she came with her friend which I didn’t remember her name but I know she lived in Gastonia, NC and I cried and said I was sorry for not remembering her and she said that it was alright but I cried anyway. They visited me for three hours and it was very nice and exciting.


They did it again

I went to Bible Study tonight and I met the lady Toby, and three of the regular girls. They were talking about something godly and I started crying and I said that I don’t know nothing about the bible which I did before I had the stroke. I don’t know the versus and the numbers and they said that I did. I said no I don’t and they said when someone was talking about something I jumped in and I said something on whatever it was they were talking about. I said no I only said at that time, what was in my heart. It happen to fit the conversation. And then Toby suggested I needed prayer again. We gathered in a circle and she said something to God.

I think I’m getting comfortable with the girls from my Bible Study. They let me cry and don’t say anything. They let me recover from my crying on my own. Thats nice.


I went to Virginia to visit my mother who is 87 years old. She is going through Alheimer Disease. She is staying with my sister and half the time she doesn’t know her. When I was crying my mother would say what are you crying for, stop that crying and she would be hollering at me. When I say Mommy I can’t just stop until I’m finish. But I know she doesn’t understand so I just don’t let her she me crying any more.

My sister, my neices and everyone was there. It was a very nice time. I am glad I went. I had an awesome time there.


I cry. Recovery

how do you feel as
hurdles you have had to get over
thing you find really hard
all types of things like this.

1. The things I find that is really hard for me was setting up a website that
was almost impossible for me to do. I could not remember this or that.
My son set up my website for me and he didn’t really know how but he did
it anyway. On Saturday and Sundays I have to go with my husband to play bingo
and I couldn’t talk to any one because I would cry and I did not want all
those people seeing me cry so I just didn’t talk. If I had a bingo my
husband would yell bingo for me because I could not yell it for myself.
Sometimes I still have a tendency to cry but mostly I don’t.

2.The hurdles I had to get over with my crying was my husband and my son. I
didn’t care about anyone else but them. Whenever I had to speak to my son I cried.
How can I cry to speak to my own child. That was very hard for me. Extremely hard.
He would always say I understand you cry when you say something to anybody not only
me but he didn’t understand that I didn’t want to cry when I spoke to him he was my
child from birth.

Where my other hurdle came in was with my husband, how can I cry with my husband.
I was married to him for 14 years and I couldn’t explain to him good enough what
I was actually crying about. I would take him to work and pick him up. Sometimes
I would cry and sometimes not. If he only said hello when he got into the car,
I would cry. He really didn’t understand it. He would tell me to stop crying all
the time, but of course I could not until I was actually finished crying. It is
and was a nightmare.

3. All types of things like this would make me cry like when I go to the supermarket.
The girl at the checkerout counter would ask me for my phone number and I would
start crying. I go the health food supermarket and they ask me for something and I cry.
I go to the pharmacy and they ask me something, I cry. I go pay a loan for my husband,
and ask me something, I cry. I go to pizza hut for something and they ask me something,
I cry. Every where I go, I cry. Isn’t that crazy. I’m sorry but if you have what
I have its just plain crazy


Doctor’s note

Ms. Brathwaite:
I am sorry that you have had a hard time to find me. Yes I have
studied pathological laughing and crying syndrome and your case sounds
close to what I have seen in many of my patients.
Before I can help you further, please provide me with the following
– report of your most recent MRI (if you have the actual scans on a
CD, that would help me greatly)
– triggers for your crying/ actual examples from daily life
– any change in your mood when you cry/ or before you cry.
– how many times a day before you started on citalopram.

to know more about your condition


Patients with various neurologic disorders exhibit exaggerated or
inappropriate episodes of laughter, crying, or both without an
apparent motivating stimulus or in response to stimuli that would
not have elicited such an emotional response before the onset of
the underlying disease. During these episodes, patients have
difficulty controlling their emotional expression according to the
contextual information. In contrast, patients with mood disorders
have a pervasive and sustained change in their emotional experience
and thus exhibit spells of laughter or crying because of an
underlying mania or depression. This article focuses on the clinical
presentation, diagnosis, prevalence, and proposed pathophysiological
mechanisms of and available treatment options for this
clinical phenomenon.
Mayo Clin Proc. 2006;81(11):1482-1486
MSA = multiple system atrophy; PLC = pathological laughter and crying
Many patients with neurologic disorders exhibit uncontrollable
episodes of laughing, crying, or both
that are either exaggerated or contradictory to the context in
which they occur. Patients report that their episodes are at
best only partially amenable to voluntary control, and unless
they experience a severe change of mental status, they
often have insight into their problem and judge their emotional
display as inappropriate and out of character.
The cardinal feature of the disorder is a pathologically
lowered threshold for exhibiting the behavioral response of
laughter, crying, or both. An affected individual exhibits
episodes of laughter and/or crying without an apparent
motivating stimulus or in response to stimuli that would not
have elicited such an emotional response before the onset
of their underlying neurologic disorder. In some patients,
the emotional response is exaggerated in intensity but is
provoked by a stimulus with an emotional valence congruent
with the character of the emotional display. For example,
a sad stimulus provokes a pathologically exaggerated
weeping response instead of a sigh, which the patient
normally would have exhibited in that particular situation.
However, in some other patients, the character of the emotional
display can be incongruent with, and even contradictory
to, the emotional valence of the provoking stimulus or
may be incited by a stimulus with no clear valence. For
example, a patient may laugh in response to sad news or cry
in response to stimuli with no emotional undertone, or,
once provoked, the episodes may switch from laughing to
crying or vice versa.
Various terms have been used interchangeably to describe
the problem of laughing and crying in these patients. The
most widely used terms are pseudobulbar affect, pathological
laughter and crying, emotional lability, emotionalism,
and emotional dysregulation. Terms such as forced crying,
involuntary crying, pathological emotionality, and emotional
incontinence have also been used, although less
frequently. In some instances, authors have used the same
term for clinically different conditions, and in other instances,
different terms have been used synonymously to
describe the same clinical presentation. Because the disorder
is primarily a problem with laughing and crying
rather than exhibiting all kinds of emotional displays, the
displays are out of character and disproportionate to the
context in which they occur, and the condition can lead to
social and personal distress and functional impairment,
we use the term pathological laughter and crying (PLC)
in this article, which we believe is a clear and concise
descriptor of the condition and has historical roots in classical

Accurate estimates of the incidence and prevalence of PLC
in the setting of each specific neurologic disorder are lacking.
This may be in part due to confusion in the literature
about the nosology and terminology of this clinical condition,
as described previously. This confusion notwithstanding,
there appears to be considerable potential for errors in
estimating the incidence and prevalence of impaired emotional
regulation. Patients and their family members may
be unaware that such episodes develop in the context of
neurologic disorders.1 If clinical researchers do not ask
specifically about symptoms of impaired emotional regulation
and if the nosological distinctions described previously
are not considered, these symptoms may be either
unrecognized or misinterpreted as a symptom of a mood
disorder. Conversely, some studies have attempted to estimate
the prevalence of the problem generally in clinical
referral samples, which may lead to overestimates of the
incidence and prevalence of this disorder.
With these caveats in mind, it is informative to review
the reported scope of the problem in some neurologic disorders.
Among patients with traumatic brain injury,2,3 the
prevalence of this condition during the first year after injury
is estimated at 5% to 11%. The disorder occurs in 10%
of patients with multiple sclerosis,4-6 49% of patients with
amyotrophic lateral sclerosis,7 11% to 34% of patients with
stroke,8-10 5% of patients with Parkinson disease and the
noncerebellar type of multiple system atrophy (MSA),11
and 37% of patients with the cerebellar type of MSA.12
The scope of the problem in patients with dementia is
controversial. In one report,13 the authors defined the problem
as simply “observable sudden changes in emotional
expressions,” which they observed in about 74% of mildly
to moderately impaired patients with Alzheimer disease.
Starkstein et al14 used the Pathological Laughter and Crying
Scale15 in their study of 103 patients with Alzheimer
disease. Of these 103 patients, 40 had PLC. Of note, however,
21 of these 40 patients also had an underlying congruent
mood disorder. The authors labeled these patients
as having “emotional lability,” which they defined as
“pathological laughing and crying with an underlying
mood disorder.”
Despite the problems associated with accurately estimating
the incidence and prevalence of PLC, the limited
data available suggest that this problem occurs with a frequency
considerably higher than is generally recognized by
physicians. In light of the frequency of the neurologic
conditions in which impaired regulation of emotional expression
develops, numerous patients may be expected to
have PLC and might benefit from its identification and
Several scales are available to identify and characterize
PLC.15-17 Among these, the 2 most commonly used in clinical
research studies are the Pathological Laughter and Crying
Scale15 and the Center for Neurologic Study-Lability
Scale.15-17 The items included in these scales cover the
triggering factors, frequency, duration, and involuntariness
of PLC events, issues that overlap minimally with items
included in scales for the assessment of mood disorders
(for example, the Hamilton Depression Rating Scale and
the Beck Depression Inventory), supporting the differences
in these diagnostic constructs.
Assessment scales developed specifically for characterizing
the problem of laughing and crying may be useful in
clinical trials. Using such scales to screen patients at risk
for PLC and to follow their progress may also be practical.
However, we strongly believe that the diagnosis of the
condition remains a bedside issue. As suggested by the
content of assessment scales for this disorder, a single
screening question regarding the presence of frequent
laughing or crying spells may be sufficient to identify
patients with impaired regulation of emotional expression.
Once the patient’s answer is confirmatory, other routine
questions are warranted to discern whether the patient’s
uncontrollable episodes of laughing or crying are related to
an underlying mood disorder.
In the clinical setting, PLC is often unrecognized. In cases
in which the physician notices spells of uncontrollable
laughing or crying, the condition can often be misdiagnosed
as a mood disorder. However, a thorough evaluation
can lead to proper differentiation of these 2 conditions.
Mood is an emotional state sustained over relatively long
periods, days to weeks or more. Patients with depression
feel depressed most of the time, and thus their emotional
display of crying is primarily a reflection of their underlying
depressed mood. By contrast, patients with pathological
crying exhibit the emotional display in the absence of a
pervasive and sustained depressed mood. The crying occurs
only paroxysmally and is uncontrollable and involuntary.
Such episodes may even occur in the absence of any
congruent changes in the mood of the patient. Crying due to
depression is associated with signs such as anhedonia,
decreased energy, psychomotor slowing, feelings of hopelessness
and helplessness, and suicidal ideation as well as
poor concentration and anxiety. Likewise, patients with
bipolar disease may exhibit laughter or crying during their
cycles of cheerfulness, irritability, and depression. In addition,
these patients have associated problems of grandios-

ity, poor judgment, hyperactivity, pressured speech, poor
sleep, and increased energy. Patients with PLC report none
of these symptoms and, in fact, are often embarrassed by
their episodes of laughing or crying.
Importantly, although PLC and mood disorders appear
to be different clinical entities, they may coexist in the
same patient.12,15,18 Robinson et al15 reported that almost
half of their patients with PLC had coexisting depression.
However, resolution of pathological laughing or pathological
crying seems to be independent of the resolution of
depression in these patients and has no relationship with
the changes in anxiety or aggression scores.15 A recent
study found that all patients with the cerebellar type of
MSA who exhibited pathological laughter and/or crying
also had depression.12
The coexistence of pathological emotional expression
(eg, PLC) and pathological emotional experience (eg,
mood disorders) is an important observation because it
poses limitations in diagnosis and research and will certainly
influence the physician’s choice of treatment.
Pathological laughter and crying often responds to the
same treatments used for mood disorders. However, in
patients with PLC, the beneficial effects of these medications
are evident within days of treatment initiation and
occur in response to much lower dosages than those usually
prescribed for the treatment of mood disorders.12,15,18,19
Schiffer et al18 studied the effect of amitriptyline, a
tricyclic antidepressant, in 12 multiple sclerosis patients
with PLC using a mean dosage of 58 mg/d and compared
its effect to that of placebo in a 30-day, double-blind,
crossover study. They reported a significant improvement
in PLC symptoms in 8 patients taking amitriptyline with no
effect on their coexisting depression. Robinson et al15 administered
nortriptyline in dosages as high as 100 mg/d in
14 stroke patients with PLC and compared its effectiveness
to placebo in 14 other patients with stroke. They
reported significantly greater improvement of PLC in patients
given nortriptyline than in those receiving placebo
and no significant change in the depression status of these
Selective serotonin reuptake inhibitors have also been
used for treatment of PLC. In an open-label study by
Seliger et al,20 all 13 patients (8 with stroke and 5 with
multiple sclerosis) who received 20 mg/d of fluoxetine
reported a decrease in the number of laughing or crying
episodes within 3 to 14 days. Andersen et al21 compared
citalopram, 10 to 20 mg/d, to placebo in 16 consecutive
patients with stroke in a crossover study. They found that
daily crying episodes decreased by 50% in all 13 patients
receiving citalopram compared to only 2 patients who received
placebo. In a double-blind, placebo-controlled
study, Burns et al22 determined that sertraline in dosages up
to 50 mg/d was effective in 13 of 14 patients with PLC and
stroke, whereas placebo produced a beneficial response in
9 of 14 patients (P=.041). Muller et al23 conducted an openlabel
study of 26 patients with PLC after traumatic brain
injury. Thirteen patients were treated with citalopram, and
13 others received paroxetine in a single daily dose of 10 to
40 mg. Significant improvement was seen in 92% of patients,
with rapid onset of effect within 1 to 3 days.
AVP-923 is a new compound that consists of 30 mg of
dextromethorphan and 30 mg of quinidine, which inhibits
the metabolism of dextromethorphan by cytochrome P-450
2D6 enzyme. In a recent randomized, double-blind study
by Brooks et al,24 140 patients with amyotrophic lateral
sclerosis and PLC were randomized to receive dextromethorphan
plus quinidine (n=70) vs dextromethorphan
(n=33) or quinidine (n=37) alone in twice-daily doses. The
authors reported approximately 2-fold lower scores on the
Center for Neurologic Study-Lability Scale in the group
that received dextromethorphan plus quinidine compared
to the groups receiving only dextromethorphan or quinidine.
Moreover, 52% of the patients receiving dextromethorphan
plus quinidine were symptom free during the
last 2 weeks of the study compared to 23% of patients
taking dextromethorphan alone and 12% of patients taking
quinidine alone. Statistically significant improvement in
quality-of-life and quality-of-relationship scores were seen
in the patients receiving the combination treatment compared
to those receiving either drug alone. Adverse effects
reported in the group receiving dextromethorphan plus quinidine
included nausea (33%), dizziness (20%), and somnolence
(13%), resulting in a 24% discontinuation rate in the
group receiving the combination regimen compared to 6%
and 5% in the dextromethorphan and quinidine groups,
respectively. In a study by Panitch et al,25 150 patients with
multiple sclerosis and PLC were randomized to receive
dextromethorphan plus quinidine (n=76) or placebo (n=74).
Patients receiving the active compound experienced significant
improvement of their PLC symptoms as well as
their quality-of-life and relationship scores. Laughing and
crying episodes occurred 4.7 times per week in the group
receiving dextromethorphan plus quinidine compared to
11.5 episodes per week in the placebo group. Headaches
were the most commonly reported adverse effect in both
groups, but the only statistically significant adverse event
was dizziness (26.3% in the dextromethorphan plus quinidine
group vs 9.5% in the placebo group). Discontinuation
of the study medication because of adverse events occurred
in 16% of the dextromethorphan plus quinidine group compared
to 11% in the placebo group.

In summary, although several agents have been shown
to be effective in the treatment of PLC, head-to-head
comparative clinical trials are needed to determine whether
any of the aforementioned treatment options are superior in
efficacy or adverse-effect profile.
Given the therapeutic effect of serotonergic agents in patients
with PLC, it has been suggested that a serotonergic
dysfunction is responsible for the impaired emotional regulation
in these patients.21 The fact that a chemical agent,
such as serotonin, is helpful in treating a condition does not
necessarily imply a causal relationship between the agent
and the condition. However, understanding how serotonergic
substitution can improve emotional experience in patients
with mood disorders while also being effective in
patients who have pathological regulation of emotional
expression is important.
The hypothesis proposed by Oppenheim and
Siemerling26 in 1886 and subsequently by Kinnier Wilson27
in 1924 was that impaired emotional regulation results
from disinhibition of a presumed brainstem center for
laughter and crying due to lesions of the voluntary motor
pathways in the descending corticobulbar tracts. As previously
published,28 this explanation has several limitations.
For example, if the inhibitory pathways are damaged in
these patients, why do they not laugh or cry constantly, or
why do they sometimes exhibit a response contradictory to
the emotional valence of the triggering stimulus? Moreover,
why do many patients with this condition lack the
typical features of pseudobulbar palsy? The hypothesis of
disinhibition assumes that a proper operation of emotional
expression is based on a balance between inhibitory and
excitatory inputs to a presumed brainstem center for laughing
and crying. On the basis of the current knowledge of
brain anatomy and function, there is no single brainstem
center for laughter and crying. Rather, a network of
brainstem nuclei is involved in the generation of movements
associated with the acts of laughter or crying, and it
remains to be determined how this network is regulated by
the cerebral cortex. Which cortical structures are involved,
and how do they exert their control over the brainstem
network? Feinstein et al6,29 have shown that the involuntary
and uncontrollable emotional behavior in patients with
multiple sclerosis correlates directly with poor performance
in tests of prefrontal function. This suggests that the
prefrontal cortices, rather than the primary motor cortices
as Oppenheim and Siemerling26 and Kinnier Wilson27 had
suggested, are important for the control of emotional behavior.
30 However, questions remain. For instance, to what
extent and through which pathways do the prefrontal cortices
regulate the operation of the brainstem network? Is this
regulation made possible through direct corticobulbar pathways
or indirectly through additional structures such as the
cerebellum, as suggested recently?12,28,31
A thorough understanding of the etiology and pathophysiology
of PLC awaits further elucidation of the neural
basis of human emotion and of the neurotransmitters and
networks involved in its regulation and coordination.
Meanwhile, the recognition, diagnosis, and treatment of
this clinical entity is important to help patients and their
caretakers enhance their quality of life and relationships.
