When to See a Doctor

Seek professional care if you experience any of the following symptoms

• Strange behaviour

Possible Causes

Generally, Strange behaviour can be related to:

• Sydenham Chorea

  Sydenham chorea is a rare neurological disorder characterized by sudden onset abnormal movements that occur after infection with group A streptococcus bacteria. Most people are affected during childhood. Movements are random, continuous, and involuntary, sometimes affecting the entire body. The disease is thought to occur because antibodies against group A streptococcus cross-react with nerve cells in the basal ganglia, a structure in the brain that fine-tunes voluntary movements.

• Attention Deficit Hyperactivity Disorder (ADHD)

  Attention deficit hyperactivity disorder (ADHD) is a condition that is characterized by attention difficulty, hyperactivity, and inability to control one's behavior (impulsiveness). It often starts in childhood and can cause a child to struggle in school, at home, or in social relationships. It is more common in male children. The causes of ADHD remain unclear but risk factors include genetic factors, tobacco use during pregnancy, premature delivery, and low birth weight.

• Alzheimer's Disease

  Alzheimer's disease is the most common cause of dementia. The brain shrinks, affecting memory and behavior. Symptoms worsen over time and can interfere with daily life. Increasing age raises the risk for Alzheimer dementia.

• Dissociative Disorder
• Frontotemporal Dementia
• Sleepwalking
• Urea Cycle Disorder
• Diffuse Axon Injury

Related Serious Diseases

Sometimes, Strange behaviour may be related to these serious diseases:

• Epilepsy

  Epilepsy is a neurological disorder where brain activity becomes abnormal, causing seizures of varying durations and severities. It can affect people of any age and may be caused by genetic disorders or brain injuries, such as stroke.

• Wernicke Encephalopathy
