People who have certain mental health conditions such as substance-induced psychosis , schizophrenia , and post-traumatic stress disorder PTSD , can also experience flashbacks.
In some cases, flashbacks are caused by an underlying physical condition such as migraines, brain lesions, or a seizure disorder. Specific disturbances in one or more senses sight, hearing, taste, smell, and touch can be brought on by eye conditions, neurological diseases, hearing problems, and stroke. If you are experiencing hallucinations, getting a timely and accurate diagnosis is crucial. While most of the physical and mental health conditions that can cause hallucinations, including drug use can be managed or treated, some can have serious consequences if left untreated.
People who experience flashbacks may feel a great deal of distress and even fear that they are losing touch with reality. However, it's important to know that many of the conditions that can cause these visual disturbances—including drug use—are treatable. If you are experiencing flashbacks, whether or not you have taken LSD or another drug, talk to your doctor.
