There are several types of bipolar and related disorders. They may include mania or hypomania and depression. Symptoms can cause unpredictable changes in mood and behavior, resulting in significant distress and difficulty in life.
- Bipolar I disorder. You’ve had at least one manic episode that may be preceded or followed by hypomanic or major depressive episodes. In some cases, mania may trigger a break from reality (psychosis).
- Bipolar II disorder. You’ve had at least one major depressive episode and at least one hypomanic episode, but you’ve never had a manic episode.
- Cyclothymic disorder. You’ve had at least two years — or one year in children and teenagers — of many periods of hypomania symptoms and periods of depressive symptoms (though less severe than major depression).
- Other types. These include, for example, bipolar and related disorders induced by certain drugs or alcohol or due to a medical condition, such as Cushing’s disease, multiple sclerosis or stroke. (Mayo Clinic)
Schizoaffective disorder symptoms may vary from person to person. People with the condition experience psychotic symptoms, such as hallucinations or delusions, as well as symptoms of a mood disorder — either bipolar type (episodes of mania and sometimes depression) or depressive type (episodes of depression).
The course of schizoaffective disorder usually features cycles of severe symptoms followed by periods of improvement with less severe symptoms.
Signs and symptoms of schizoaffective disorder depend on the type — bipolar or depressive type — and may include, among others:
- Delusions — having false, fixed beliefs, despite evidence to the contrary
- Hallucinations, such as hearing voices or seeing things that aren’t there
- Symptoms of depression, such as feeling empty, sad or worthless
- Periods of manic mood or a sudden increase in energy with behavior that’s out of character
- Impaired communication, such as only partially answering questions or giving answers that are completely unrelated
- Impaired occupational, academic and social functioning
- Problems with managing personal care, including cleanliness and physical appearance (Mayo Clinic)
