Barriers to treatment: the unique challenges for physicians providing dementia care.

Evaluating and treating dementia is intellectually demanding and enormously satisfying. However, physicians providing dementia care also confront unique challenges that cause discomfort and overwhelming frustration unless they are recognized and overcome. Physicians must care for individuals who do not adopt the "sick role." They must establish and maintain rapport with patients while also approaching collateral sources to obtain a complete history. They must develop a complex alliance with the patient, caregivers, community agencies, and other health professionals to provide effective treatment. Physicians must relate "bad news" to several people at once who are unequally prepared for it, while dealing with their own diagnostic uncertainty. Furthermore, physicians must honor patient autonomy and balance it with the needs of caregivers. Since the demands of providing dementia care are not typical of most medical practice, the special attributes needed are often not taught to students or adequately reimbursed by health insurance. The quality of dementia care will improve when strategies that address these aspects of care for patients with dementia are widely adopted.
