Possible causes
- Dissociative disorder
Dissociative disorder is a mental disorder that involves experiencing a disconnection and lack of continuity between thoughts, memories, surroundings, actions, and identity. People with dissociative disorder escape reality in ways that are involuntary and unhealthy, causing problems with functioning in everyday life.
- Alzheimer dementia (AD)
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.
- Schizophrenia
A mental disorder with changed brain function. The exact cause is unknown, but a mix of genetic, psychological, and environmental factors are likely responsible.
- Mild cognitive impairment (MCI)
- Hyperactivity disorder

Cerebral infarction refers to damage to brain tissue resulting from a stroke. It occurs due to decreased blood supply and oxygen delivery to the brain, causing brain cell death and brain damage. It is typically caused by a blood clot or fatty/cholesterol plaques blocking a blood vessel to the brain, but can also occur if a blood vessel ruptures and bleeds into the brain.
