'Til death do us part: intimacy and sexuality in the marriages of Alzheimer's patients.

1. Alzheimer's disease (AD) is likely to have a significant effect on sexual behavior, but both patient and partner will still have sexual feelings and needs. 2. Research has shown that a high proportion of men with AD develop erection problems, but causes of their erection difficulties are not understood. 3. Research has shown that inappropriate sexual behavior in AD patients is uncommon, although it can be very troubling to the family and health-care provider if it occurs. 4. More professionals need to be trained to discuss sexual issues openly and sensitively with AD patients and partners and to offer useful clinical suggestions.
