What is Serious Mental Illness (SMI)?
SMI refers to mental health disorders that significantly disrupt a person’s ability to perform critical life activities. These include but are not limited to:
Schizophrenia: Schizophrenia is a chronic and severe mental health disorder characterized by distortions in thinking, perception, emotions, language, sense of self, and behavior. Common symptoms include hallucinations (often hearing voices), delusions (false beliefs), and disorganized thinking. Schizophrenic patients might also experience apathy, lack of emotion, and impaired cognitive abilities. The exact cause of schizophrenia is unknown, but it is believed to be a combination of genetics, brain chemistry, and environment. Schizophrenia is typically diagnosed in late adolescence to early adulthood and is more common in men. Treatment usually involves a combination of antipsychotic medications and psychotherapy.
Bipolar Disorder: Bipolar disorder is a mental illness marked by extreme mood swings from high (manic or hypomanic) to low (depressive) and vice versa. These mood episodes can affect sleep, energy, activity, judgment, behavior, and the ability to think clearly. Bipolar disorder is categorized into several types, including Bipolar I, Bipolar II, and cyclothymic disorder, based on the severity and nature of mood episodes. The causes are not fully understood but include a combination of genetics, environment, and altered brain structure and chemistry. Treatment typically involves a combination of medication, such as mood stabilizers, and psychotherapy.
Major Depression: Major depression, also known as major depressive disorder or clinical depression, is a common but serious mood disorder. It causes severe symptoms that affect how one feels, thinks, and handles daily activities such as sleeping, eating, or working. Symptoms must be present for at least two weeks for a diagnosis of depression. These include persistent sadness, hopelessness, fatigue, changes in appetite or weight, difficulty sleeping or oversleeping, loss of interest in activities, and thoughts of death or suicide. The exact cause is unknown but likely involves a combination of genetic, biological, environmental, and psychological factors. Treatment typically involves medications, psychotherapy, or a combination of both.
Severe Anxiety Disorders: Severe anxiety disorders encompass various conditions marked by excessive fear or anxiety. They include disorders such as generalized anxiety disorder (GAD), panic disorder, social anxiety disorder, and specific phobias. Symptoms may include persistent worry, nervousness, rapid heartbeat, sweating, trembling, and gastrointestinal issues. These disorders can significantly impair daily functioning. While the exact cause is not known, contributing factors may include genetics, brain chemistry, personality, and life events. Treatment typically involves psychotherapy, such as cognitive-behavioral therapy, medication, or a combination of both.
