Alzheimer's disease (AD) poses a major clinical challenge because of its high prevalence in the aging population, its prolonged course, and the absence of curative treatment. Important advances have recently beendrug therapy Aging mft CEU course made, however, in the diagnosis of the disease and the elucidation of its neuroscientific basis. Genetic research has identified an allele of apolipoprotein E that may confer a higher risk of developing AD. In addition, new possibilities for treatment are being investigated. One drug therapy--tacrine--has been approved, although uncertainty lingers about its efficacy and safety. In the absence of effective medical treatment, AD is a difficult problem for patients and their families. However, the physician can help by providing emotional support, symptom management, and informed counseling.  

Dr. Filley CM. Alzheimer's disease: It's irreversible but not untreatable. Geriatrics 1995; 50(July):18-23. An unfortunate tendency to consider Alzheimer s disease (AD) one of the "untreatable" dementias persists in the medical literature. However, if we required all of our patients to have entirely curable illnesses, few indeed would qualify for treatment. There is no untreatable disease, although AD is among the many that are irreversible. Effective pharmacotherapy may someday be available, but there is much you can do now for AD patients and their families.
Recent years have witnessed significant advances in our understanding of AD:

  • Diagnosis has improved considerably by careful attention to clinical features of the disease, thus facilitating appropriate decision-making and clinical research.
  • Much progress has been made toward understanding the cause of AD, without which definitive treatment will remain elusive.
  • Finally, the drug tacrine HC1 (Cognex) has provided the first therapeutic approach that may alter the course of the disease in some patients.

Treatment approaches: Counseling, drug therapies
Intervention with a patient presenting with probable AD can begin at the first encounter. Carefully consider the details of the clinical history, as this assures the patient that the evaluation is comprehensive and helps build confidence that you will continue to be available for advice and guidance.

Counseling. After you have excluded reversible causes of dementia by appropriate tests, clarify and explain the diagnosis, even though this initially may be difficult for patients and families to accept. Informed and sympathetic counseling allows for some appreciation of the problems that may arise, the approximate time course of the disease, and what kind of adjustments may be necessary.

As the disease advances, it is important to bring up the issue of advance directives while the patient still has decision-making capacity. The two most common advance directives are the durable power of attorney for health care, which allows a family member or other person to make healthcare decisions in the event of the patient's incapacity, and the living will, which instructs medical personnel to with-old or withdraw death-delaying procedures when the patient is in a terminal state and unable to communicate his or her wishes.

Referral to appropriate community resources, such as the Alzheimer's Association, can provide significant support and further information for patients and families as they grapple with progressive neurobehavioral decline. Educational materials such as The 36-Hour Day[17] and Understanding Alzheimer's Disease[18] are of great help. For legal and financial protection, many families obtain advice from an attorney who is knowledgeable in elder law.

Continuing follow-up of AD patients will usually involve your participation in the resolution of issues such as driving ability, legal competency, nursing home placement, and termination of care; problems such as these highlight the vital role in AD of caregivers--usually the family--who also need your attention as the "second victims" of the disease.
Drug therapy. Symptomatic pharmacotherapy is useful for certain complications of AD, with the proviso that elderly demented patients are quite susceptible to adverse drug reactions. In general, drugs that increase confusion, notably benzodiazepines and anticholinergic agents, should be avoided.

Conclusion
As a major cause of morbidity and mortality among older adults, AD has become an enormous medical challenge. Because its etiology remains uncertain, curative therapy is not available, but much progress has been made in the clinical diagnosis of the disease and in elucidating aspects of its patho-physiology. As knowledge expands, exciting prospects such as neuro-protective therapy, nerve growth factor,[24] and even gene therapy[26] may become a reality.
Today, a great deal can be done in less dramatic ways. Emotional support, symptom management, and informed counseling are invaluable to those who are afflicted and their families. Tacrine and other palliative drugs may find a secure role as well. Until the cause and cure of AD are discovered, it is well to remember that there is no untreatable disease.

Hibernating ground squirrels provide clues to new stroke treatments - November 18, 2017
In the fight against brain damage caused by stroke, researchers have turned to an unlikely source of inspiration: hibernating ground squirrels. While the animals' brains experience dramatically reduced blood flow during hibernation, just like human patients after a certain type of stroke, the squirrels emerge from their extended naps suffering no ill effects. Now, scientists have identified a potential drug that could grant the same resilience to stroke patients.
Naturally occurring molecule may help prevent, treat atherosclerosis and gum disease - November 16, 2017
Resolvin E1, a molecule produced naturally in the body from an omega -3 fish oil, topically applied on gum tissues not only prevents and treats gum disease, but also decreases the likelihood for advanced arterial atherosclerotic plaques to rupture and form a dangerous thrombus or blood clot, report investigators.
How bacteria in the gut influence neurodegenerative disorders - November 16, 2017
Humans have roughly as many bacterial cells in their bodies as human cells, and most of those bacteria live in the gut. New research released today reveals links between the gut microbiome -- the population of microorganisms living in the gastrointestinal tract -- and brain diseases such as Parkinson's and Alzheimer's, including potential new ways to track and treat these diseases.
Uninsured heart attack, stroke patients face ‚Äėcatastrophic‚Äô costs - November 16, 2017
Heart attack and stroke patients without medical insurance face ‚Äúdevastating‚ÄĚ health care costs that can bankrupt them, research shows.
Virtual reality training may be as effective as regular therapy after stroke - November 15, 2017
Using virtual reality therapy to improve arm and hand movement after a stroke is equally as effective as regular therapy, according to a study.
