Visual Hallucinations

Visual hallucinations are experiences where a person sees things that aren't actually there. These can range from simple flashes of light to complex images, like people or animals. They often occur in conditions such as schizophrenia, Parkinson's disease, severe sleep deprivation, or certain medications. While the person experiencing them may feel convinced of their reality, these perceptions are created by the brain due to various factors, including changes in brain chemistry or structure. Understanding visual hallucinations is important for diagnosing and treating the underlying conditions that may cause them.
