Dementia is a group of conditions that cause a decline in cognitive functioning, which includes thinking, remembering, and problem-solving. The most common form of dementia is Alzheimer’s disease.
Symptoms of dementia include memory loss, difficulty expressing thoughts, and becoming confused or disoriented. Some people with dementia may become aggressive at times and have trouble regulating their emotions.
Psychosis can also be a complication of dementia. Psychosis refers to the mental state where someone is not sure what’s real or not. It can include paranoid or delusional thoughts as well as hallucinations.
Managing and treating dementia-related psychosis requires understanding, patience, and a variety of different approaches. We’ll go over what researchers know so far about why this symptom occurs in dementia, and how it can be addressed.
Approximately 5.8 million people in the United States have recevied a diagnosis of dementia. Researchers believe that number will double by 2060. A significant portion of people with dementia will likely experience psychosis at some point.
Rates of dementia-related psychosis depend on several issues, such as:
•type of dementia
•stage or severity of dementia
•individual risk factors, including other health conditions
One 2021 study indicates 20 to 70 percent of people with dementia will experience psychosis as part of the condition.
Psychosis symptoms often depend on the type of dementia a person has. Their overall health and complicating risk factors may also impact how symptoms develop. In short, each person’s experience will be different.
Symptoms of dementia-related psychosis may include:
•hallucinations (visual, auditory, or olfactory)
•delusional thinking (false beliefs)
•paranoia (being irrationally suspicious)
•agitation or aggression
It’s unclear what causes some people with dementia to develop psychosis but not others. However, a few potential causes have been identified.
In people with Alzheimer’s disease, atypical deposits on the brain may be related to psychosis. These can interfere with the brain’s signaling. People with Alzheimer’s disease are more likely to experience delusions.
Lewy body dementia is the result of plaque deposits or “Lewy bodies” on the brain. They impact the brain’s chemical messaging system. Visual hallucinations are a common symptom of psychosis in people with this type of dementia.
Dementia related to Parkinson’s disease could be connected to medications. People with Parkinson’s disease often take dopamine-enhancing medications for some symptoms, including stiffness and walking issues. However, some of these medications may cause the onset of psychosis symptoms.
There is no standardized treatment for dementia-related psychosis. Psychosis is a complicated phenomenon that does not have a simple cure.
Instead, doctors may rely on caregivers to help the affected person with dementia understand what they’re experiencing. Certain strategies can limit potential triggers for psychosis and prevent stressful, emotional situations from getting out of control.
These strategies may include:
•Adjusting the environment. If someone with dementia has recurring symptoms of psychosis, it may help to eliminate any potential triggers for those experiences.
•For example, if they “see” other people in the room after catching a glimpse of themselves in the mirror, cover reflective surfaces.
•If dark, shadowy corners of the house worry them, use lights to illuminate these spaces.
Dementia-related psychosis can be difficult to diagnose. Symptoms may be mistaken for other health conditions, such as anxiety and depression. People with dementia may conceal some of their symptoms and be hesitant to admit they’re seeing or hearing things others aren’t.
While psychosis is common in people with the memory-related conditions, there are few effective medical treatments. Lifestyle adjustments, caregiving, and certain medications can help manage episodes of dementia-related psychosis.
Understanding that many people with dementia experience some symptoms of psychosis and learning how to recognize those signs may help affected people and caretakers prepare.
It also encourages compassion and understanding as loved ones and medical professionals sort through the impacts of psychosis and how it interacts with other symptoms of dementia.
