Personality variables in patients with self-reported reactions to dental amalgam.

Personality variables in persons with self-reported reactions to dental amalgam (amalgam patients, n = 26, 17 F, 9 M) and in others without such symptoms (controls, n = 21, 14 F, 7 M) are compared. The groups were comparable regarding age, education, and amount of amalgam. Minnesota Multiphasic Personality Inventory-2 (MMPI-2) profiles were obtained for all subjects.

Memory functions in persons with dental amalgam.

Memory and psychophysiological variables in persons with self-reported reactions to dental amalgam (amalgam patients: N=26) and in persons without such symptoms (controls: N=21) were compared. The groups were matched regarding age, education, and amount of amalgam. Wechsler Memory Scale-Revised was obtained for all subjects and compared to amalgam points in a dose-response design.

Neuropsychological deficits in HIV-1 seropositive and seronegative intravenous drug users (IVDUs): a follow-up study.

Human immunodeficiency virus type 1 (HIV-1) seropositive AIDS free and HIV-1 seronegative intravenous drug users were tested twice with a comprehensive neuropsychological test battery. Only minor group differences were found. Memory difficulties were the most pronounced difference with lower scores in the HIV-1 seropositive group.

[Clinical neuropsychology].

The article reviews the development of clinical neuropsychology as a professional discipline and comments on important contributions from various research fields and clinical disciplines. The consequences of disturbances in the neurotransmitter systems for neuropsychological functioning are discussed, as well as various clinical issues and the applications of clinical neuropsychology, and of neuropsychological evaluations.

Psychological difficulties related to human immunodeficiency virus-1 infection in intravenous drug users.

Psychopathology and emotional changes were examined over a 9-month period in this study of human immunodeficiency virus-1 (HIV-1) infection in seronegative and seropositive intravenous drug users. The HIV-1-seropositive group showed more psychological difficulties and emotional distress at both testings. For the HIV-1-seronegative subjects, a trend for less psychopathology and psychological distress was found.

Neuropsychological deficits in HIV-1 seropositive and seronegative intravenous drug users.

A battery of neuropsychological tests was administered to detoxified HIV-1 seropositive and seronegative intravenous drug users. There were few problems related to administering the test battery to the groups in question. Of the total sample, 28% obtained an Halstead-Reitan Impairment Index > .

Neuropsychologic effects of saturation diving.

Neuropsychologic status of saturation divers was assessed before and after 300-500 msw dives (deep saturation diving--DSD group) and before and after 3.5 yr of ordinary saturation diving (saturation diving--SD group). Average baseline results showed the divers to be slightly superior to nondiving controls.

Left and right-handed dyslexic boys: an empirical test of some assumptions of the Geschwind-Behan hypothesis.

Twenty-six dyslexic boys (13 left-handers and 13 right-handers) were tested for hemispheric asymmetry with dichotic listening (DL) and a visual half-field test (VHF). The purpose of the study was an empirical test of the Geschwind-Behan [Proc. natn.

MMPI profiles in migraine before and after biofeedback treatment. Minnesota Multiphasic Personality Inventory.

Migraine has been associated with specific personality traits. Typically, migraine patients show elevation on the "neurotic scales" on the MMPI, and the profiles usually reported can be classified as "psychosomatic". A crucial matter is whether certain personality traits predispose to headache problems or whether they are an effect of such problems.

Activation, arousal, and neuropsychological rehabilitation.

This paper addresses the concept of arousal and the role of the reticular system in producing the orienting response. For patients with deviant autonomic responses, the use of central neuropharmacological stimulants is considered. Their therapeutic value is discussed in relation to hyperactive children and individual adult cases of the posttraumatic syndrome consequent upon traffic accidents.

MMPI patterns in chronic muscle pain, tension headache, and migraine.

MMPI personality profiles were obtained from three clinical groups (n = 79). One group consisted of men and women with chronic muscle pain (MP; n = 34), a second group of male and female chronic tension headache patients (TH; n = 12), and a third group of female migraine patients (M; n = 33). The M group was subdivided on the basis of source of referral and into groups of classic versus common migraine.

Differential neuropsychological effects of diving to 350 meters.

Six divers were compressed on heliox to 350 m. Repeated neuropsychological and neurological tests were conducted during the dive. Averaged increased tremor during the compression was found.

The effect of the stimulant drugs, dextroamphetamine and methylphenidate, on secretion of growth hormone in hyperactive children.

The stimulant effect of L-dopa (125 to 500 mg) was compared to dextroamphetamine and methylphenidate, 15, and 20 mg, respectively, on growth hormone secretion in 20 hyperactive children. All three stimulants were responsible for peak GH concentration in serum at 60 minutes after drug ingestion; there was no significant difference between the mean GH level at any time of sampling. Seven of the children were retested with L-dopa and dextroamphetamine after six to eight months of treatment with methylphenidate.
