2.1 Introduction
The onset of senility involves the impact of deteriorating physical and physiological efficiency of all the systems in the body, leading to degenerative disorders. One such disorder of the brain is dementia, a Latin term originally meaning “madness” (de-, “without”+ment, the root of mens, or “mind”), which is characterized by a serious loss of global cognitive ability in a previously unimpaired person. Identified as one of the types of senile dementia, the disease was first described by the German psychiatrist and neuropathologist Alios Alzheimer in 1906 and later became commonly known as Alzheimer’s disease (AD). AD is a slowly progressive old-age disease of the brain characterized by the impairment of memory and, eventually, disturbances in reasoning, planning, language, and perception.
2.1.1 Dementia
While AD is one of the most common types of dementia, it is a challenge to diagnose. The term “dementia” encompasses many mental disabilities, disorders, or malfunctions of the brain.
●
Symptoms of dementia must include decline in memory and in at least one of the following cognitive abilities:
●
to speak coherently or understand spoken or written language
●
to recognize or identify objects, assuming intact sensory function
●
to perform motor activities, assuming intact motor abilities and sensory function and comprehension of the required task
●
to think abstractly, make sound judgments, and plan and carry out complex tasks.
●
The decline in cognitive abilities must be severe enough to interfere with daily life.
Different types of dementia are associated with distinct symptom patterns and brain abnormalities, and include AD, vascular dementia, dementia with Lewy bodies, frontotemporal lobar degeneration, mixed dementia, Parkinson’s disease, Creutzfeldt-Jacob disease, and normal pressure hydrocephalus. AD and other types of dementias are irreversible, with no cure, and current available treatments help only in improving quality of life for AD patients.
2.1.2 Symptoms of Alzheimer’s Disease
While AD may affect people in different ways, the most common symptom pattern begins with a gradually worsening ability to remember new information. This occurs as the neurons that begin to die and malfunction are the neurons involved in forming new memories. As neurons in other parts of the brain malfunction and die, individuals experience other difficulties. The following are common symptoms of Alzheimer’s:
