Dementia hallucination and the causes?

Dementia hallucination is caused when the brain gets damaged by disease. The common symptoms are progressive impairment of memory, behavior and thinking that affect one’s ability to carry out everyday activities. Generally dementia affects only people who are more than 65 years of age. Early onset is noticed in some cases even at the age of 50s, 40s or 30s. Early diagnosis and proper treatment can slow down the progression of the disease and maintain normal functionality to some extent.


Diagnosing dementia and identifying its type is a challenging task. People are considered to suffer from dementia when they show cognitive impairment and become unable to perform their daily functions like taking medicines, driving safely and paying their bills.

To diagnose the reason for dementia the doctor has to recognize the pattern of the losing of skills etc. and determine what the patient is able to do him. Presently biomarkers are available which can be used to make a more accurate diagnosis of Alzheimer’s disease.

Your doctor will be conducting a physical examination after reviewing your symptoms and medical history. He will ask someone who is very close to you about your symptoms also. No single test is there which can diagnose dementia. So doctors often conduct a number of tests with an intention to pinpoint the problem.


The cause of dementia is attributed to the loss or damage of nerve cells and their connectives in the brain. Depending upon the brain’s area affected by the damage, dementia affects the people in different manners and show different symptoms.

Dementia's are often classified by what they commonly have like proteins deposited in the brain or part of the brain that is affected by dementia. Some dementia cases like those caused as a result of reaction to some medications or caused because of vitamin deficiencies will improve with treatment.


Dementia is generally not a curable disease. But there are easy methods to manage the symptoms shown by the patients.


Cholinesterase inhibitors: These inhibitors generally work by boosting the levels of the chemical messenger involved in judgment and memory. These medications are primarily used for Alzheimer’s disease, they are also prescribed for other dementias including Parkinson's disease and Lewy body dementia. Nausea, diarrhea, vomiting etc. are the common side effects. Slow heart rate, sleep disturbances and fainting are other possible side effects.

Memantine: Memantine works by controlling the activity of glutamate, a chemical messenger related to brain functions like memory, learning etc. In some cases doctors prescribe memantine along with some inhibitors. The common side effect of this medication is dizziness.


Many of the dementia symptoms and behavioral problems can be treated initially making use of non-drug approaches like:

Occupational therapy: An occupational therapist tries to show how your home can be made safer and he also teaches coping behaviors. The purpose is to stop accidents like falls, prepare the patient for dementia progression and manage the behavior.

Modifying the environment:

It becomes easier for a person with dementia to concentrate better if the clutter and noise around him is reduced. Objects that can be a threat to personal safety like car keys, knives etc have to be kept hiding. They can also keep monitoring systems capable of alerting if a person with dementia is wandering.

Simplifying tasks: The tasks can be broken into smaller one and one has to focus on success only. Structure and routine is also capable of reducing confusion among people with dementia.

Lifestyle Remedies

It has been found that dementia symptoms and the behavioral problems associated with dementia progress overtime. The following suggestions can be tried by caregivers.
