ANXIETY DISORDERS
Anxiety is a normal emotion. It’s your brain’s way of reacting to stress and alerting you of
potential danger ahead.
Everyone feels anxious now and then. For example, you may worry when faced with a problem at
work, before taking a test, or before making an important decision.
Occasional anxiety is OK. But anxiety disorders are different. They’re a group of mental
illnesses that cause constant and overwhelming anxiety and fear. The excessive anxiety can make
you avoid work, school, family get-togethers, and other social situations that might trigger or
worsen your symptoms.
With treatment, many people with anxiety disorders can manage their feelings.
The main symptom of anxiety disorders is excessive fear or worry. Anxiety disorders can also
make it hard to breathe, sleep, stay still, and concentrate. Your specific symptoms depend on
the type of anxiety disorder you have. 
MOOD DISORDERS
A mood disorder is a mental health problem that primarily affects a person’s emotional state. It
is a disorder in which a person experiences long periods of extreme happiness, extreme sadness,
or both.
It is normal for someone’s mood to change, depending on the situation. However, to be diagnosed
with a mood disorder, symptoms must be present for several weeks or longer. Mood disorders can
cause changes in your behavior and can affect your ability to deal with routine activities, such
as work or school.Two of the most common mood disorders are depression and bipolar disorder.Mood
disorders such as depression and bipolar disorder may recur or be ongoing and therefore may
require long-term or lifetime treatment. It is important to take your medications as
prescribed.
Seek help immediately if you feel suicidal or have thoughts of harming yourself
or others.
SCHIZOPHRENIA
Schizophrenia is a serious mental disorder in which people interpret reality abnormally.
Schizophrenia may result in some combination of hallucinations, delusions, and extremely
disordered thinking and behavior that impairs daily functioning, and can be disabling.
People with schizophrenia require lifelong treatment. Early treatment may help get symptoms
under control before serious complications develop and may help improve the long-term outlook.
Schizophrenia involves a range of problems with thinking (cognition), behavior and emotions.
Signs and symptoms may vary, but usually involve delusions, hallucinations or disorganized
speech, and reflect an impaired ability to function.Suicidal thoughts and behavior are common
among people with schizophrenia.
If you have a loved one who is in danger of attempting
suicide
or has made a suicide attempt, make sure someone stays with that person.

aging.A person with dementia may show any of the symptoms listed below, mostly due to memory
loss.

EATING DISORDERS
Eating disorders are real, complex medical and psychiatric illnesses that can have serious
consequences for health, productivity and relationships.
Eating disorders, including anorexia nervosa, bulimia nervosa, binge eating disorder and OSFED
(other specified feeding or eating disorder), are bio-psycho-social diseases-- not fads, phases
or lifestyle choices.
People struggling with an eating disorder often become obsessed with food, body image and/or
weight. These disorders can be life-threatening if not recognized and treated appropriate.Eating
disorders are treatable, and earlier diagnosis and intervention often leads to better outcomes.
The most effective and long-lasting treatment for an eating disorder is some form of
psychotherapy or counseling, coupled with careful attention to medical and nutritional needs.
Ideally, whatever treatment is offered should be tailored to the individual; this will vary
according to both the severity of the disorder and the patient's individual problems, needs and
strengths.
Treatment must address the eating disorder symptoms and medical consequences, as well as
psychological, biological, interpersonal and cultural forces that contribute to or maintain the
eating disorder. 
PSYCHOTIC DISORDERS
Psychotic disorders are a group of serious illnesses that affect the mind. They make it hard for
someone to think clearly, make good judgments, respond emotionally, communicate effectively,
understand reality, and behave appropriately.
When symptoms are severe, people with psychotic disorders have trouble staying in touch with
reality and often are unable to handle daily life. But even severe psychotic disorders usually
can be treated.
Doctors don't know the exact cause of psychotic disorders. Researchers
believe that many things play a role. Some psychotic disorders tend to run in families, which
means that the disorder may be partly inherited. Other things may also influence their
development, including stress, drug abuse, and major life changes.
