Dementia refers to the impairment of at least two aspects of brain function, including memory, attention, orientation, language, the ability to get things done, etc. Most of the dementia symptoms worsen gradually, but in some cases the deterioration could be more rapid. Apart from affecting the person’s memory, demented patients will progressively lose reasoning, critical thinking skills and their ability to live their daily life independently.
The most common form of dementia affecting the elderly is Alzheimer’s disease, for which there is currently no cure. Up until today the key treatments focus on delaying the deterioration by adjusting the patient’s environment to ensure their mental and physical safety, as well as offering assistance to relatives and caregivers on how to prepare for the behavioral changes which the patient will undergo as the condition progresses.
