Synopsis The CAMCOG, the cognitive section of the Cambridge Examination for Mental Disorders of the Elderly (CAMDEX), was administered twice to 53 patients with a clinical diagnosis ranging from no dementia to severe dementia. The stability of the total CAMCOG score was high (0·97). Patients with less than moderate dementia were differentiated well by the total score and by subscales with a range of more than 8 points, except when education was low or age was higher than 78. Because performance on most (sub)scales is modified by age and education level, stratified norms are desirable. Only the Praxis subscale, and specifically performance on drawing tasks, appeared to be influenced by depression.

Patients with multiple sclerosis reported less left ear numbers but more right ear numbers than controls in a dichotic listening test. The multiple sclerosis patients were also relatively impaired on three learning tasks; one of these, a test for paired-associate learning of names and faces, correlated with left ear findings; the results are interpreted as supporting a hypothesised disconnection mechanism.

Alexithymie scheint mit einer autonomen Dysfunktion assoziiert zu sein, hoher sympathotonischer Erregung und einer Entkopplung zwischen physiologischer und emotionaler Erregung [131,[133][134][135][136][137][138][139] Prävalenz der Alexithymie bei Multipler Sklerose Das Vorkommen der Alexithymie bei MS Patienten ist bereits in den 1980er Jahren beschrieben worden [145,146]. Folgestudien vor dem Hintergrund der weiter oben erwähnten Konnexionismustheorie (rechte ‚ganzheitliche' versus linke ‚analytische' Hemisphäre) und den Erkenntnissen über eine defiziente interhemisphärische Übertragung [147][148][149][150], zeigten eine mögliche Rolle der interhemisphärischen Übertragung beim Auftreten der Alexithymie [151] und einer veränderten interhemisphärischen Übertragung [149,[152][153][154][155][156][157] Alexithymie, klinische und demografische Charakteristika Die bisher genannten Arbeiten zeigen eine hohe Variabilität der klinischen Charakteristika wie Alter, Geschlecht, Erziehung, Krankheitsdauer, EDSS, oder Anzahl der Schübe zwischen alexithymischen und nicht-alexithymischen MS Patienten und gesunden Kontrollpersonen. ...

... The CAMCOG-R added several executive items and made a few changes, while maintaining the original scoring system (Roth et al., 1998). The CAMCOG/CAMCOG-R demonstrates impressive psychometric properties (Hendrie et al., 1988;Huppert et al., 1995Huppert et al., , 1996Lindeboom et al., 1993;Roth et al., 1986). There is an optimal cut-off -79/80 out of 105 or 106to distinguish subjects with cognitive impairment from those with no impairment (Hendrie et al., 1988;Pereiro et al., 2015;Roth et al., 1986). ...
