The difference between Alzheimer’s Disease and Dementia

on March 10, 2014

There are many misconceptions about Alzheimer’s Disease (AD) and dementia. Dementia is actually a set of symptoms which arises from a number of conditions or diseases. AD is one of those diseases. In fact, it is the most common cause of dementia . Other diseases include vascular dementia, Parkinson’s Disease, Lewy Body and Pick’s Disease. Brain disorders such as Huntington’s Disease and AIDS can also result in dementia. The diseases are degenerative, meaning the symptoms will get worse over time.

Some causes of dementia are reversible. Reactions to prescription medications, chronic alcohol abuse, thyroid conditions, vitamin deficiencies, brain tumors or water on the brain (hydrocephalus) when successfully treated, can result in the return of brain function.

Dementia symptoms involve more than just difficulty remembering things. The symptoms have to be strong enough to get in the way of accomplishing normal daily tasks. Memory loss, a short attention span, inability to plan or follow a sequence of instructions, finding the right words, and personality changes are just some of the problems faced by a person with dementia. The symptoms cause a change in the person’s abilities compared to what they could do befor.

When a doctor diagnoses a person with AD, it means that the person’s symptoms and test results show that it is highly likely the brain will show the pathological features (plaques and tangles) of AD.

There is no cure for AD, but treatment of the disease and the symptoms of dementia are advancing over time. It is important to consult a physician as early as possible if there a suspicion that a change in the ability to think and recall are getting in the way of handling demands of everyday living. Medications such as the Exelon patch, Namenda and Aricept can be prescribed to slow the progression of the disease.
