[Clinical aspects and prognosis in cerebellar concussion syndromes].

In a group of 100 cases of head trauma 4 patients (4%) were observed with traumatic cerebellar syndromes without coexistence of other traumatic focal lesions in the central nervous system. All these cases were due to cerebellar contusion. In 2 patients the diagnosis was confirmed by computerized tomography. The clinical observations indicate that these syndromes are not associated with raised intracranial pressure, but have a rich symptomatology, frequently exceeding the picture of selective cerebellar damage. The observations made as yet seem to suggest that computerized tomography is the only auxiliary investigation making possible the diagnosis of selective cerebellar contusion. In uncomplicated cerebellar contusion the prognosis is good.

[Redox and proteolytic enzymes in brain tissue after a concussion].

The article deals with the results of histochemical study of some redox and proteolytic enzymes (SDH, MDH, NAD-diaphorase, LDH, and acid and alkaline phosphatase) in experiments on animals in various periods after infliction of a craniocerebral injury and on autopsy material, i.e. the brain of patients who had died from severe craniocerebral injury incompatible with life. It is shown that the activity of all enzymes decreases (SDH, MDH, NAD-diaphorase, and alkaline phosphatase) or increases (LDH, acid phosphatase) in various periods after the injury. The results were compared with the findings of morphological examination of the same brain areas performed by means of neurohistological methods.

Sleep-awake patterns following cerebral concussion.

This study compared sleep-awake patterns in clients following head injury with their sleep-awake patterns prior to head injury. Data were collected from 75 subjects who had experienced a minor head injury (MHI) with a disturbance in consciousness three months prior to filling out a questionnaire. The majority of the clients were males, 16 to 30 years old, who had been involved in a motor vehicle accident which resulted in MHI. Questions related to the sleep-awake patterns before and after head injury. Sleep-awake patterns following head injury differed from sleep-awake patterns prior to head injury in the following sleep indicators: sleep interruptions per week and per night increased significantly (p less than .004, p less than .001) as did the time needed to function at peak efficiency upon awakening (p less than .001). The subjects reported significant increases (p less than .02) in the number of times per month in which they were unable to return to sleep after an early morning awakening coupled with the difficulty in returning to sleep (p less than .04). Overall, the clients reported significantly decreased sleep quality (p less than .02) and increased complaints about sleep following head injury (p less than .001). An increase in the time of consciousness disruption following head injury was related to the subjects having a tendency to sleep longer and to recall fewer, less vivid dreams. A decreased level of consciousness upon admission to the emergency department at time of injury correlated with the increased number of arousals during the sleep cycle and the reduced intensity of auditory stimulus needed to interrupt sleep. The anatomical site of the head injury and the duration of post-traumatic amnesia (PTA) were found to have no significant effect upon sleep-awake patterns following MHI.
