What Are The Major Types Of Dementia?

Dementia is a term used to describe when the loss of certain behavioral abilities, remembering, thinking, and reasoning causes interference in an individual's daily activities and life. Several cognitive functions are affected when an individual develops dementia, including language skills, problem-solving, ability to focus, memory, visual perception, nonverbal communication skills, and self-management. Dementia patients may experience changes in their personality and may experience difficulty in controlling their emotions. The severity of a patient's dementia can range from mild cognitive impairment and occasional forgetfulness to severe stages where they are entirely dependent on others in their basic activities of daily life. Dementia develops when neurons in the brain become non-functional, lose the ability to communicate with other cells in the brain, and die. Some neuron loss due to aging is normal and natural, but dementia defines an excessive and much greater neuron loss.
