Monitoring of long-term motor activity in depressed patients.

Wrist motor activity was continuously recorded by a solid-state monitor in 12 patients with major depression throughout their stay in hospital; their clinical state was evaluated using three scales. During the day, activity troughs and immobility peaks occurred before noon and around 1500 hrs. Activity level progressively increased, while the duration of immobility decreased, with clinical improvement. The immobility measurement appeared to be a valuable index of depression and is more sensitive than the activity level, mainly for agitated depressed patients. Immobility episodes during the day could suggest the release of an ultradian sleep-wake rhythm in depression.

[Narcolepsy and the psychiatric tableau. A specific form of narcolepsy?].

Narcolepsy is a well-known hypersomnia. Nevertheless narcolepsy in which the hallucinatory component is unusually prominent may lead to a false diagnosis of schizophrenia syndrome. This aspect is illustrated by the case of Miss B. who appears like a psychotic patient without dissociation syndrome and with a hysterical personality. Are the narcoleptics with psychiatric disorders a peculiar sub-type of narcolepsy? Fourty-five percent of our eleven narcoleptics patients have an associated psychiatric disorder. Most of them are depressive. Surprisingly fourty percent of our patients are non-DR2 at the Human Leucocyte Antigen typing. Furthermore seventy five percent of them have an associated psychiatric disorder. This would mean a peculiar sub-type of narcolepsy.

Circadian aspects of motor activity in depressed patients.

Wrist motor activity was continuously monitored in 10 major unipolar depressed inpatients. Clinical state and motor activity parameters were studied. The data obtained at the beginning of the hospitalization, before the antidepressant treatment, were compared to chose found just before discharge. Time of day effect and subtypes of depression (endogenous versus non-endogenous) were considered. Motor retardation is related to both fluctuations of activity level and high number of 15 minute immobility epochs. Immobility parameters at night and during day were a good indicator of the severity of the depressive state. The temporal pattern of activity level was related to the subtype of depression.
