What is Dementia
There can be least doubt about the fact that Dementia can be really scary and confusing. Dementia is accountable for the loss of independence and freedom and can be a real burden on the affected individuals as well. There are many types of Dementia. One is sure to remain amazed to come in terms with the verity that a few types of Dementia are reversible as well.
Cognitive Dementia caused due to alcohol, drugs, hormonal imbalances, depression and vitamin imbalances are reversible. It is a pleasant surprise to come in terms with the truth that it is possible to avoid as well as delay the occurrence of Dementia. The functioning of human brain gets affected because of Dementia. It generally causes the loss of mental ability of an individual.
The affected area of mental health includes problem-solving ability, attention, and memory loss. The general symptoms of Dementia are as follows:
- Communicative Difficulties
- Memory Loss
Dementia results in memory loss. The affected patient may forget the way back from the shop too. Such a patient finds it difficult to remember places and names as well. A Dementia patient finds it difficult to recollect what necessarily happened earlier during the day. The patient suffers from rapid mood fluctuations as gradually parts of the brain responsible for controlling emotions become damaged. The mood fluctuation in an affected individual suffers from anxiety and fear. A patient suffering from Dementia and displaying communicative difficulties finds it hard to write and read. Slowly, with the gradual progress of Dementia, the ability of the patient to carryout everyday task diminishes.
Dementia is caused owing to a few diseases. The diseases are mentioned below:
- Alzheimer’s Disease
- Dementia with Lewy Bodies
- Motor Neurone Disease
- Multiple Sclerosis
- HIV and AIDS
- Creutzfeldt-Jakob Disease
The most important cause of Dementia is perhaps Alzheimer’s disease. The brain of an individual affected with Alzheimer’s disease slowly undergoes a radical change and the cells of the brain die prematurely. Vascular problems also result in Dementia as the brain cells slowly die and thus hamper the supply of oxygen rich blood.
Effect of Lewy Bodies
Lewy bodies are spherical bodies that damage brain tissue. Thus, presence of Lewy bodies also affects the concentration, speaking ability and concentration of an individual. Primarily, there are two main forms of Dementia.
The two main forms of Dementia include Sub cortical Dementia and Cortical Dementia. In case of Sub cortical Dementia, brain beneath the cortex gets affected and as a result, the patient experiences an overall change in the personality. In case of cortical Dementia, cerebral cortex gets affected. Cerebral cortex is the outer layer of human brain. CJD and Alzheimer’s disease are both forms of Dementia.
