Dementia and hallucinations have a connection in some individuals, with about 10% of people who have dementia experiencing hallucinations. Dementia is a term that describes a progressive and slow decline in one’s mental abilities. A hallucination is an experience during which an individual believes they are seeing, hearing, smelling, or feeling something that is not there.
A variety of medical conditions can cause dementia. Many conditions lead to irreversible dementia that gets progressively worse, including Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, and permanent brain damage caused by tumors or head injuries. Other types of dementia can be reversed, such as dementia caused by vitamin deficiencies, removable brain tumors, toxins, excessive drug or alcohol use, and brain hemorrhages. Some people with major depression also show signs that mimic dementia.
Symptoms of dementia include memory problems, difficulty with speech, feeling disoriented, and displaying inappropriate or disruptive behavior. Dementia is most common in individuals over the age of 65. When dementia is irreversible, mental function usually deteriorates over two to 10 years. Depending on the cause of the dementia, treatment may be available to slow the rate of decline. Dementia in early states usually begins with forgetting recent events and struggling with proper judgment and abstract thinking, and as the condition worsens, some sufferers begin to struggle with dementia and hallucinations.
Hallucinations are a symptom of psychosis, which is a disturbance in the thought process and perception. Mental illnesses such as schizophrenia and psychotic depression can cause hallucinations. Hallucinations can also result from drug and alcohol use, epilepsy, high fever, serious illness, and dementia.
There are many types of hallucinations that cause an individual to perceive things that don’t exist. Types of hallucinations include auditory hallucinations, during which voices are heard; olfactory hallucinations, during which smells and smells are experienced; and visual hallucinations, during which one sees something. With individuals who have dementia and hallucinations, the most common type is visual hallucinations.
Caring for someone suffering from dementia and hallucinations can be extremely challenging. If a hallucination does not cause fear or anxiety, it is best for the caregiver to do nothing. For hallucinations that are upsetting, it is recommended that caregivers use the “Three Rs” method to reassure, respond, and reorient patients with dementia.
For example, if a man with dementia believes he or she saw someone poison his food, the caregiver should begin by calmly telling him or her that he or she was there and saw no one around his or her food. Next, the caregiver should respond by offering to check the kitchen or talk to the nurses to see if they’ve observed anything. Finally, the caregiver should return the patient’s attention to an enjoyable activity, such as watching television or working on a word search puzzle.
