What are different syndromes?
There are many different syndromes, each with its own unique set of symptoms and characteristics. Some of the most common syndromes include:
* Down syndrome is a genetic disorder that occurs when a person has an extra copy of chromosome 21. It can cause a range of physical and developmental problems, including intellectual disability, short stature, and distinctive facial features.
* Autism spectrum disorder (ASD) is a neurodevelopmental disorder that affects a person's ability to communicate and interact with others. It can also cause repetitive behaviors, restricted interests, and sensory sensitivities.
* Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder that affects a person's ability to pay attention, control impulsive behavior, and sit still. It can also cause hyperactivity and/or inattention.
* Tourette syndrome is a neurodevelopmental disorder that is characterized by tics. Tics are involuntary, repetitive movements or vocalizations. They can vary in severity and frequency, and may include such things as eye blinking, head shaking, coughing, or swearing.
* Obsessive-compulsive disorder (OCD) is an anxiety disorder that causes a person to have intrusive thoughts and compulsive behaviors. The intrusive thoughts are often distressing and may cause the person to feel anxious or fearful. The compulsive behaviors are rituals that the person feels compelled to perform in order to reduce anxiety.
* Schizophrenia is a mental illness that affects a person's thoughts, feelings, and behavior. It can cause delusions, hallucinations, disorganized speech, and social withdrawal.
* Bipolar disorder is a mental illness that is characterized by episodes of mania and depression. During manic episodes, a person may have increased energy, decreased need for sleep, racing thoughts, and impulsive behavior. During depressive episodes, a person may experience low mood, loss of interest in activities, changes in appetite or sleep, and fatigue.
* Borderline personality disorder (BPD) is a mental illness that is characterized by unstable emotions, impulsivity, and difficulty forming relationships. People with BPD may also experience intense feelings of emptiness, self-harm, and suicidal thoughts.
* Antisocial personality disorder (ASPD) is a mental illness that is characterized by a disregard for the rights of others, impulsivity, and aggression. People with ASPD may also have a history of criminal behavior.
