About the Symptom
Abnormal behavior refers to being aware or told that one has been acting strangely or differently from usual. Such behavior is often regarded as evidence of a mental or emotional disturbance, ranging from minor adjustment problems to severe mental disorder.
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 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.
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.
Related serious diseases
Sometimes, Strange behaviour may be related to these serious diseases:
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.
Acute Encephalopathy
