Schizo-Affective Disorder
This is my "main" disorder, the
one that took the longest to diagnose, and the one whose treatment improved
my life a thousandfold. Once I went on anti-psychotic drugs, many
of my problems all but disappeared (hearing voices, hearing God in my head,
paranoia, irrational thoughts and beliefs). Below is the NAMI (National
Alliance for the Mentally Ill) fact
sheet about schizoaffective disorder. I've also included their
information about schizophrenia and bipolar
disorder, since schizoaffective disorder is somewhat of a cross between
the two.
What is Schizoaffective Disorder?
Some psychiatric disorders are
very difficult to diagnose accurately. One of the most confusing conditions
is schizoaffective disorder. This relatively rare disorder is defined
as "the presence of psychotic symptoms in the absence of mood changes for
at least two weeks in a patient who has a mood disorder." The diagnosis
is used when an individual does not fit diagnostic standards for either
schizophrenia or "affective" (mood) disorders such as depression and bipolar
disorder (manic depression).
Some people may have symptoms
of both a depressive disorder and schizophrenia at the same time, or they
may have symptoms of schizophrenia without mood symptoms.
Many individuals with schizoaffective
disorder are originally diagnosed with manic depression. If the person
experiences delusions or hallucinations that go away in less than two weeks
when the mood is "normal," bipolar disorder may be the proper diagnosis.
Someone who experiences psychosis for three or four weeks while in a manic
phase does not have schizoaffective disorder.
However, if delusions or hallucinations
continue after the mood has stabilized and are accompanied by other symptoms
of schizophrenia such as catatonia, paranoia, bizarre behavior, or thought
disorders, a diagnosis of schizoaffective disorder may be appropriate.
Accurate diagnosis is easier once the acute psychotic episode is under
control.
Distinguishing between bipolar
disorder and schizophrenia can be particularly difficult in an adolescent,
since at that age psychotic features are especially common during manic
periods.
Because schizoaffective disorder
is so complicated, misdiagnosis is common. Some people may be misdiagnosed
as having schizophrenia. Others may be misdiagnosed as having bipolar disorder.
And those diagnosed as having schizoaffective disorder may actually have
schizophrenia with prominent mood symptoms. Or they may have a mood disorder
with symptoms similar to those of schizophrenia.
What is the treatment for this disorder?
Psychiatrists often treat this
disorder with an anti-psychotic medication and lithium, or with carbamazepine
(an anticonvulsant medication) and lithium. As a practical matter,
differentiating between schizophrenia, bipolar disorder, and schizoaffective
disorder is not absolutely critical, since antipsychotic medication is
recommended for all three. If a mood problem is suspected, lithium or an
antidepressant should be added.
What is the prognosis for those with
this disorder?
The prognosis for individuals
diagnosed with schizoaffective disorder is generally better than for those
diagnosed with schizophrenia, but not quite as good for those diagnosed
with a mood disorder. (Schizophrenia is a chronic brain disorder interfering
with a persons' ability to think clearly, manage emotions, make decisions,
and relate to others. Persons with schizophrenia may experience hallucinations
and delusions. Mood disorders, including depression and bipolar disorder,
are chronic illnesses in which the person's mood may return to "normal"
between depressive or manic episodes.) Those with schizoaffective disorder
generally respond to lithium better than those with schizophrenia, but
not as well as those with mood disorders. More research is needed to fully
understand this illness and why it resists conventional treatment. New
medications may be developed to treat this disorder more effectively.
Schizophrenia
What is schizophrenia?
Schizophrenia is a devastating
brain disorder that affects approximately 2.2 million American adults,
or 1.1 percent of the population age 18 and older. Schizophrenia interferes
with a person's ability to think clearly, manage emotions, make decisions,
and relate to others. The first signs of schizophrenia typically emerge
in the teenage years or twenties. Most people with schizophrenia suffer
chronically or episodically throughout their lives, and are often stigmatized
by lack of public understanding about the disease. Schizophrenia is not
caused by bad parenting or personal weakness. A person with schizophrenia
does not have a "split personality," and almost all people with schizophrenia
are not dangerous or violent towards others when they are receiving treatment.
What are the symptoms of schizophrenia?
No one symptom positively identifies
schizophrenia. All of the symptoms of this illness can also be found in
other brain disorders. For example psychotic symptoms may be caused by
the use of drugs, or may be characteristics of a manic episode in bipolar
disorder. However, when a doctor sees the symptoms of schizophrenia and
carefully assess the course of the illness over six months, he or she can
almost always make a correct diagnosis.
The symptoms of schizophrenia
are generally divided into three categories, including positive, disorganized
and negative symptoms.
Positive Symptoms, or "psychotic"
symptoms, include delusions and hallucinations because the patient has
lost touch with reality in certain important ways. "Positive" as used here
does not mean "good." Rather, it refers to having overt symptoms that should
not be there. Delusions cause the patient to believe that people are reading
their thoughts or plotting against them, that others are secretly monitoring
and threatening them, or that they can control other people's minds. Hallucinations
cause people to hear or see things that are not there.
Disorganized Symptoms include
confused thinking and speech, and behavior that does not make sense. For
example, people with schizophrenia sometimes have trouble communicating
in coherent sentences or carrying on conversations with others; move more
slowly, repeat rhythmic gestures or make movements such as walking in circles
or pacing; and have difficulty making sense of everyday sights, sounds
and feelings.
Negative Symptoms include
emotional flatness or lack of expression, an inability to start and follow
through with activities, speech that is brief and lacks content, and a
lack of pleasure or interest in life. "Negative" does not, therefore, refer
to a person's attitude, but to a lack of certain characteristics that should
be there.
What are the causes of schizophrenia?
Scientists still do not know the
specific causes of schizophrenia, but research has shown that the brains
of people with schizophrenia are different, as a group, from the brains
of people without the illness. Like many other medical illnesses such as
cancer or diabetes, schizophrenia seems to be caused by a combination of
problems including genetic vulnerability and environmental factors that
occur during a person's development.
How is schizophrenia treated?
While there is no cure for schizophrenia,
it is a highly treatable and manageable illness. However, people may stop
treatment because of medication side effects, disorganized thinking, or
because they feel the medication is no longer working. People with schizophrenia
who stop taking prescribed medication are at a high risk of relapse into
an acute psychotic episode.
Hospitalization. People who experience
acute symptoms of schizophrenia may require intensive treatment including
hospitalization. Hospitalization is necessary to treat severe delusions
or hallucinations, serious suicidal thoughts, an inability to care for
oneself, or severe problems with drugs or alcohol.
Medication. The primary medications
for schizophrenia are called antipsychotics. Antipsychotics help relieve
the positive symptoms of schizophrenia by helping to correct an imbalance
in the chemicals that enable brain cells to communicate with each other.
As with drug treatments for other physical illnesses, many patients with
severe mental illnesses may need to try several different antipsychotic
medications before they find the one, or the combination of medications,
that works best for them.
Conventional Antipsychotics were
introduced in the 1950's and all had similar ability to relieve the positive
symptoms of schizophrenia. Most of these older "conventional" antipsychotics
differed in the side effects they produced. These conventional antipsychotics
include chlorpromazine (Thorazine), fluphenazine (Prolixin), haloperidol
(Haldol), thiothixene (Navane), trifluoperazine (Stelazine), perphenazine
(Trilafon), and thioridazine (Mellaril).
New "Atypical" Antipsychotics.
In the last decade new "atypical" antipsychotics have been introduced.
Compared to the older "conventional" antipsychotics these medications appear
to be equally effective for helping reduce the positive symptoms like hallucinations
and delusions - but may be better than the older medications at relieving
the negative symptoms of the illness, such as withdrawal, thinking problems,
and lack of energy. The atypical antipsychotics include risperidone (Risperdal),
clozapine (Clozaril), olanzapine (Zyprexa), quetiapine (Seroquel), and
ziprasidone (Geodon).
Current treatment guidelines recommend
using one of the atypical antipsychotics other than clozapine as a first
line treatment option for newly diagnosed patients. However, for people
already taking a conventional antipsychotic medication that is working
well, a change to an atypical may not be the best option. People thinking
of changing their medication should always consult with their doctor and
work together to develop the most safe and effective treatment plan possible.
Psychosocial Rehabilitation. Research
shows that people with schizophrenia who attend structured psychosocial
rehabilitation programs and continue with their medical treatment manage
their illness best. One of the most effective psychosocial approaches for
the most severely ill or those with both mental illness and substance abuse,
is the Program for Assertive Community Treatment (PACT), an intensive team
effort in local communities to help people stay out of the hospital and
live independently. Available 24-hours a day, seven-days a week, PACT professionals
meet their clients where they live, providing at-home support at whatever
level is needed. Professionals work with clients to address problems effectively,
to make sure medications are being properly taken, and to meet the routine
daily challenges of life, such as grocery shopping and managing money.
PACT programs are statewide in
four states and growing in another 20 states. PACT is significantly reducing
hospital admissions, and improving functioning and the quality of life
for people with schizophrenia.
What are the side effects of the
medications used to treat schizophrenia?
All medications have side effects.
Different medications produce different side effects, and people differ
in the amount and severity of side effects they experience. Side effects
can often be treated by changing the dose of the medication, switching
to a different medication, or treating the side effect directly with an
additional medication. Common inconvenient side effects of all antipsychotic
drugs used to treat schizophrenia include dry mouth, constipation, blurred
vision, and drowsiness. Some people experience sexual dysfunction or decreased
sexual desire, menstrual changes, and significant weight gain. Other common
side effects relate to muscles and movement problems. These side effects
include: restlessness, stiffness, tremors, muscle spasms, and one of the
most unpleasant and serious side effects, a condition called tardive dyskinesia.
Tardive dyskinesia is a movement
disorder where there are uncontrolled facial movements and sometimes jerking
or twisting movements of other body parts. This condition usually develops
after several years of taking antipsychotic medications and more predominantly
in older adults. Tardive dyskinesia affects 15 to 20 percent of people
taking conventional antipsychotic medications. The risk of developing tardive
dyskinesia is lower for people taking the newer antipsychotics. Tardive
dyskinesia can be treated with additional medications or by lowering the
dosage of the antipsychotic if possible. For additional information see
our fact sheet about tardive dyskinesia.
Clozapine was the first atypical
antipsychotic in the United States and seems to be one of the most effective
medications, particularly for people who have not responded well to other
medications. However, in some people it has a serious side effect of lowering
the number of white blood cells produced. People taking clozapine must
have their blood monitored every one or two weeks to count the number of
white blood cells in the bloodstream. For this reason clozapine is usually
the last atypical antipsychotic prescribed, and is usually used as a last
line treatment for people that do not respond well to other medications
or have frequent relapses.
Bipolar Disorder
What is bipolar disorder?
Bipolar disorder, or manic depression,
is a serious brain disorder that causes extreme shifts in mood, energy,
and functioning. It affects 2.3 million adult Americans, or 1.2 percent
of the population. Bipolar disorder is characterized by episodes of mania
and depression that can last from days to months. Bipolar disorder is a
chronic condition with recurring episodes that often begin in adolescence
or early adulthood. It generally requires ongoing treatment.
What are the symptoms of mania?
Mania is the word that describes
the activated phase of bipolar disorder. The symptoms of mania may include:
-
either an elated, happy mood or
an irritable, angry, unpleasant mood
-
increased activity or energy
-
more thoughts and faster thinking
than normal
-
increased talking, more rapid
speech than normal
-
ambitious, often grandiose, plans
-
increased sexual interest and
activity
-
decreased sleep and decreased
need for sleep
What are the symptoms of depression?
Depression is the other phase
of bipolar disorder. The symptoms of depression may include:
-
depressed or apathetic mood
-
decreased activity and energy
-
restlessness and irritability
-
fewer thoughts than usual and
slowed thinking
-
less talking and slowed speech
-
less interest or participation
in, and less enjoyment of activities normally enjoyed
-
decreased sexual interest and
activity
-
hopeless and helpless feelings
-
feelings of guilt and worthlessness
-
pessimistic outlook
-
thoughts of suicide
-
change in appetite
-
change in sleep patterns
What is a "mixed" state?
A mixed state is when symptoms
of mania and depression occur at the same time. During a mixed state depressed
mood accompanies manic activation. The symptoms during a mixed state often
include agitation, trouble sleeping, significant change in appetite, psychosis,
and suicidal thinking.
What is rapid cycling?
Sometimes individuals may experience
regularly alternating periods of mania and depression. When four or more
episodes of illness occur within a 12-month period, the individual is said
to have bipolar disorder with rapid cycling. Rapid cycling is more common
in women.
What are the causes of bipolar disorder?
While the exact cause of bipolar
disorder is not known, researchers believe it is the result of a chemical
imbalance in the certain parts of the brain. Scientists have found evidence
of a genetic predisposition to the illness. Bipolar disorder tends to run
in families, and close relatives of someone with bipolar disorder are more
likely to be affected by the disorder. Sometimes serious life events such
as a serious loss, chronic illness, or financial problem, can trigger an
episode in some individuals with a predisposition to the disorder. There
are other possible "triggers" of bipolar episodes: the treatment of depression
with an antidepressant medication may trigger a switch into mania, sleep
deprivation may trigger mania, or hypothyroidism may produce depression
or mood instability. It is important to note that bipolar episodes can
also occur without an obvious trigger.
How is bipolar disorder treated?
While there is no cure for bipolar
disorder it is a highly treatable and manageable illness. After an accurate
diagnosis, most people (80 to 90 percent) can be successfully treated.
Medication is an essential part of successful treatment for people with
bipolar disorder. Maintenance treatment with a mood stabilizer substantially
reduces the number and severity of episodes for most people, although episodes
of mania or depression may occur and require a specific additional treatment.
In addition, psychosocial therapies including, cognitive-behavioral therapy,
interpersonal therapy, family therapy, and psychoeducation are important
to help people understand the illness and cope with the stresses that can
trigger episodes. Changes in medications or doses may be necessary, as
well as changes in treatment plans during different stages of the illness.
Medications used to treat mania.
Two medications commonly used to treat manic episodes of bipolar disorder
are called mood stabilizers, and they include lithium (Eskalith or Lithobid)
and divalproex sodium (Depakote).
Lithium has long been used as
a first line treatment for acute mania in people with bipolar disorder.
Lithium is effective for preventing episodes of mania from occurring and
for treating an episode after it has begun. However, for some individuals,
lithium is ineffective and for others, lithium has a variety of side effects
that may make it an undesirable treatment option.
Depakote is an anticonvulsant
that has been used to treat epilepsy since 1983, but it was approved as
a treatment for manic episodes of bipolar disorder in 1995. Depakote seems
to be as effective as lithium for treating mania and it has fewer side
effects, although it may not be appropriate for people with a history of
liver problems.
Other anticonvulsant medications
have also been found to be effective treatments for mania, including carbamazepine
(Tegretol), lamotrigine (Lamictal), gabapentin (Neurontin), and topiramate
(Topamax). However, these four medications have not been officially approved
by the FDA for the treatment of bipolar disorder and have their own side
effects.
Mania may also be treated acutely
with antipsychotic medications in addition to a mood stabilizer. More research
is needed to test the safety and efficacy of atypical antipsychotics, which
may prove to be alternatives in the long-term treatment of bipolar disorder.
Medications used to treat depression.
During depressive episodes, people with bipolar disorder may need additional
treatment with an antidepressant medication. Because of the risk of triggering
mania, doctors often prescribe lithium or an anticonvulsant mood stabilizer
with an antidepressant. Antidepressant medications relieve depression,
elevate mood, and activate behavior, but it often takes three to four weeks
to respond. Sometimes a variety of different antidepressants and doses
will be tried before finding the medication that works best for a particular
individual.
There are several different
types of antidepressants used to treat depression including tricyclic antidepressants
(TCAs), monoamine oxidase inhibitors (MAOIs), selective serotonin reuptake
inhibitors (SSRIs), or newer antidepressants that function in different
ways.
Consumers and their families must
be cautious during the early stages of treatment when energy levels and
the ability to take action return before mood improves. At this time -
when decisions are easier to make, but depression is still severe - the
risk of suicide may temporarily increase.
What are the side effects of the
medications used to treat bipolar disorder?
All medications have side effects.
Different medications produce different side effects, and people differ
in the amount and severity of side effects they experience. Side effects
can often be treated by changing the dose of the medication, switching
to a different medication, or treating the side effect directly with an
additional medication.
Side effects of medications used
to treat mania. Lithium tends to have the most side effects of the mood
stabilizers - including hand tremors, excessive thirst, excessive urination,
and memory problems - but they often become less troublesome after a few
weeks as the body adjusts to the medication. Particularly bothersome tremors
can be treated with additional medication. Low thyroid function can be
treated with thyroid supplements. In very few people, long-term lithium
treatment can interfere with kidney function.
The other anticonvulsant mood
stabilizers tend to have fewer side effects than lithium. Common side effects
include nausea, drowsiness, dizziness, and tremors. Some people taking
anticonvulsant mood stabilizers may develop liver problems or problems
with white blood cell count and blood platelets, which can be severe. Therefore,
blood tests to monitor liver function and blood cells may be an important
part of treatment with some of these medications.
Side effects of medications used
to treat depression. About half of the people taking antidepressant medications
have mild side effects during the first few weeks of treatment.
Common side effects of tricyclic
antidepressants (TCAs) include dry mouth, constipation, bladder problems,
sexual problems, blurred vision, dizziness, drowsiness, skin rash, or weight
gain or loss.
Individuals taking monoamine oxidase
inhibitors (MAOIs) may have to be careful about eating certain smoked,
fermented, or pickled foods, drinking certain beverages, or taking some
medications because they can cause severe high blood pressure in combination
with the medication. MAOIs have other, less severe side effects as well.
The SSRIs and newer antidepressants
tend to have fewer and different side effects, such as nausea, nervousness,
insomnia, diarrhea, rash, agitation, or sexual problems.
