Unusual behavior, especially if someone is repeating words or movements, can result from something that is affecting the brain or the nervous system. This could be a condition like epilepsy or Tourette's syndrome, or even the side effect of a medication. Psychiatric conditions can be the cause as well.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Autism and Communication
Autism in children and adults is a developmental disorder, characterized by impaired development in communication, social interaction, and behavior. Autism is classified as a pervasive developmental disorder (PDD), which is part of a broad spectrum of developmental disorders affecting young children and adults. There are numerous theories and studies about the cause of autism. The treatment model for autism is an educational program that is suitable to an individual's developmental level of performance. There is no "cure" for autism.
Epilepsy is a brain disorder in which the person has seizures. There are two kinds of seizures, focal and generalized. There are many causes of epilepsy. Treatment of epilepsy (seizures) depends upon the cause and type of seizures experienced.
Depression is an illness that involves the body, mood, and thoughts and affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things. The principal types of depression are major depression, dysthymia, and bipolar disease (also called manic-depressive disease).
Depression in Children
Childhood depression can interfere with social activities, interests, schoolwork and family life. Symptoms and signs include anger, social withdrawal, vocal outbursts, fatigue, physical complaints, and thoughts of suicide. Treatment may involve psychotherapy and medication.
