SUMMARY Forty-three patients with multiple sclerosis showed disturbances in short-term memory, learning, and delayed recall which were associated with years of active disease (average was 4.5 years), age, presence of flareup, but not steroid/ACTH treatment. Unrecognised memory loss might be prevalent early in the natural history of multiple sclerosis and deserves neuropsychological assessment.Cognitive decline commonly occurs in the later stages of multiple sclerosis.' In the past three decades some of the qualitative and quantitative features of cognitive change have been delineated through neuropsychological inquiry. Many investigations of intelligence in multiple sclerosis have concluded that patients with demyelination show disproportionate drops in peformance IQ while maintaining relatively good verbal skills.2 More comprehensive neuropsychological studies, utilising procedures such as the Halstead-Reitan Battery revealed patients with multiple sclerosis to have marked motor and perceptual-motor integrative deficits, generally intact verbal-language skills, and variable decrements in abstracting ability.3'0 A century has passed since Charcot first observed "enfeeblement of memory" in his patients" and " 12Gowers wrote of their "failure of memory".Despite this, the neuropsychological research reviewed above has been singularly lacking in systematic assessment of memory. Surridge'3 noted from structured psychiatric examination that approximately two-thirds of his patients showed intellectual decline, with amnesia being a central problem. Jambor's'4 related psychometric study found deficits in sentence learning and delayed recall of nonverbal information.

Results obtained from self-reported health data may be biased if those being surveyed respond differently based on health status. This study was conducted to investigate if health, as measured by health care use preceding invitation, influenced response to invitation to a 21-year prospective study, the Millennium Cohort Study. Inpatient and outpatient diagnoses were identified among more than 68,000 people during a one-year period prior to invitation to enroll. Multivariable logistic regression defined how diagnoses were associated with response. Days spent hospitalized or in outpatient care were also compared between responders and nonresponders. Adjusted odds of response to the questionnaire were similar over a diverse range of inpatient and outpatient diagnostic categories during the year prior to enrollment. The number of days hospitalized or accessing outpatient care was very similar between responders and nonresponders. Study findings demonstrate that, although there are some small differences between responders and nonresponders, prior health care use did not affect response to the Millennium Cohort Study, and it is unlikely that future study findings will be biased by differential response due to health status prior to enrollment invitation.

It is generally believed that many non-Korsakoff alcoholics have subtle defects in memory. To determine whether such defects vary as a function of length of abstinence (LOA), we performed extensive memory testing with: (1) recently detoxified (n = 31; LOA-29 days); (2) intermediate-term abstinent (n = 28; LOA = 1.9 years); (3) long-term abstinent (n = 32; LOA-7.0 years) alcoholics; and (4) nonalcoholic controls (n = 37). All subjects were matched on age and education. Alcoholics were matched on years of alcoholic drinking. Memory measures were divided into the following domains: verbal learning, verbal recall, visual learning, visual recall, and paired associate learning. A series of MANOVAs were conducted that revealed a significant relationship between visual learning and length of abstinence, and a significant interaction between age and length of abstinence on visual recall. Long-term abstinent subjects were not significantly different from controls on any test. We conclude that memory disturbance demonstrable among recently detoxified alcoholics in the early weeks of their abstinence is not evident in demographically matched long-term abstinent alcoholics with similar drinking histories.

BackgroundRecently, numerous studies have revealed an increase in complementary and alternative medicine (CAM) use in US civilian populations. In contrast, few studies have examined CAM use within military populations, which have ready access to conventional medicine. Currently, the prevalence and impact of CAM use in US military populations remains unknown.MethodsTo investigate CAM use in US Navy and Marine Corps personnel, the authors surveyed a stratified random sample of 5,000 active duty and Reserve/National Guard members between December 2000 and July 2002. Chi-square tests and multivariable logistic regression were used to assess univariate associations and adjusted odds of CAM use in this population.Results and discussionOf 3,683 service members contacted, 1,446 (39.3%) returned a questionnaire and 1,305 gave complete demographic and survey data suitable for study. Among respondents, more than 37% reported using at least one CAM therapy during the past year. Herbal therapies were among the most commonly reported (15.9%). Most respondents (69.8%) reported their health as being very good or excellent. Modeling revealed that CAM use was most common among personnel who were women, white, and officers. Higher levels of recent physical pain and lower levels of satisfaction with conventional medical care were significantly associated with increased odds of reporting CAM use.ConclusionThese data suggest that CAM use is prevalent in the US military and consistent with patterns in other US civilian populations. Because there is much to be learned about CAM use along with allopathic therapy, US military medical professionals should record CAM therapies when collecting medical history data.
