Turn off the television at times. As HD progresses, expect changes in who prepares for intimacy and who sets limits regarding time and activity together. The caregiving partner can expect ambivalent feelings and confusing thoughts. Don't forget to see the humor in a situation.
Adequate rest is extremely important.
Change in sleeping arrangements may be needed for adequate rest. The caregiving partner will need to be clear and consistent, and probably explicit, regarding expectations and limits for intimacy. Environmental cues or other subtleties may be misinterpreted by the affected person. Redirection and consistency of message are important if the affected person is preoccupied with sex in some way. Reach out for help from appropriate people if needed.
