Of the 40 million plus people in the United States over 65
years of age (about 560 million worldwide), about 5.2 million have some type of
dementia. In the United States this is
expected to double or more by 2050. Alzheimer’s
disease is the most common form of dementia.
Other types include: vascular, Lewy body, Huntington’s disease, dementia
secondary to disease (e.g. Parkinson’s disease, HIV, multiple sclerosis) or
trauma (usually repeatedly like sports head injury in football, boxing), nutritional
deficiencies, medication induced, inherited forms, and many more.
Signs and symptoms of dementia include memory problems,
decreased cognitive ability, and decreased physical activity whereby activities
of daily living (bathing, dressing, eating, household chores, etc.) may require
assistance. Personality changes like agitation, inattentiveness and
irritability are common. Dementia
diagnosis begins with a thorough history (of patient and family) and physical
examination including blood tests. Brain
scans (MRI, CT, PET) are important in helping make the diagnosis. Neurologic evaluation by a certified
neurologist is also indicated for suspected dementia. Treatment includes behavioral, occupational, and physical therapy as well as medication. In some cases such as medication induced dementia from vitamin deficiency or low thyroid levels after proper medication is given. If a drug is the cause, it will resolve by stopping the medicine. Dementia drugs can lessen the symptoms of cognitive decline, in spite of the fact that disease will usually continue to progress. Regular exercise has been shown to do improve function, also.
Preventive measures include:
- Nutritious food especially those aimed at brain health
- Physical movement and exercise
- Restful sleep
- Daily routine to include self care, meals, etc. at same time
- Intellectual stimulation like reading, conversation, brain exercises, music
- Social activities especially with family, friends
- Avoidance of smoking, too much alcohol
- Good maintenance of high blood pressure, diabetes, high cholesterol and any other diseases you may have
- Prayer and meditation
Keep your brain and body as healthy as possible in an effort
to prevent dementia. It may be
decreasing, but as we live longer the likelihood increases. Best health!
