The prevalence and spectrum of sleep problems in women with transformed migraine.

OBJECTIVES: It is our clinical observation that patients with transformed migraine (TM) almost invariably report nonrestorative sleep. In this study we sought first to validate that clinical observation, then to describe the prevalence and spectrum of factors that might contribute to nonrestorative sleep in a TM population. BACKGROUND: Although headaches have been linked with sleep problems for over a century, there is little information about the spectrum or prevalence of specific sleep problems associated with TM in adults. METHODS: We conducted a detailed sleep interview on 147 consecutive women with TM. Subjective sleep quality was assessed by asking patients to describe their state upon awakening as "refreshed" or "tired." RESULTS: None of the 147 patients reported awakening "refreshed," and 83.7% stated that they awakened "tired." Sleep complaints were prevalent and varied in this population. CONCLUSIONS: Although the relationship between pain and sleep is complex and ill understood, we found a very high prevalence of nonrestorative sleep and a similarly high prevalence of modifiable poor sleep habits in patients with TM. Since behavioral approaches have been found effective in improving sleep quality in patients with poor sleep hygiene, we propose that studies be undertaken to assess the impact of such treatment on TM.

No gender differences in the progression of nervous system disease in HIV infection.

The past decade has seen a marked increase in the number of HIV-infected women in the United States. There has been recent concern that HIV disease in general may progress more rapidly in women than men, and some studies, primarily retrospective reviews, have suggested higher rates of neurologic disease among females. The objective of this study was to assess gender differences in HIV-related central and peripheral nervous system disease over time. Participants were enrolled in a longitudinal cohort study at the University of North Carolina and had annual follow-up evaluations. At baseline, 42 HIV-negative females, 52 HIV-positive females, and 52 HIV-positive males were compared for age, education, mode of infection, absolute CD4 cell count, and plasma/cerebrospinal fluid HIV RNA load. Subjects were evaluated by standardized clinical neurologic, neuropsychological, and laboratory examinations every year. The results indicated that both HIV-positive males and HIV-positive females had poorer neurologic functioning than the control group. However, there was no evidence from the parameters measured that the rate of decline differed between HIV-positive males and HIV-positive females.

Highly active antiretroviral therapy improves neurocognitive functioning.

Although the effects of highly active antiretroviral therapy (HAART) have resulted in substantial improvements in the systemic health of patients with HIV infection, concerns remain that these medications, which cross the blood-brain barrier poorly, may have a less beneficial effect on nervous system function. This raises the possibility that there may be a progressive long-term decline in neurologic function in patients with adequate systemic response. In a prospective longitudinal study, subjects were evaluated immediately before instituting HAART. Forty-eight subjects underwent ultrasensitive HIV RNA quantitative evaluation of both plasma and cerebrospinal fluid as well as neurologic and neuropsychological examinations. They were reevaluated 6 months after treatment initiation while receiving stable HAART. Both plasma and cerebrospinal fluid viral levels significantly declined after treatment. There was significant improvement in neurologic and neuropsychological functioning after HAART. These results indicate that despite the poor central nervous system penetration of most of these agents, there is satisfactory short-term improvement in both central nervous system viral burden and nervous system function with HAART. However, because treatment failure is increasingly likely over time, continued longitudinal evaluation of this group of subjects is required.
