[Disorders of consciousness as a manifestation of neurologic disease].

Seventy-nine patients admitted in the neurological Intensive care unit because of severe disturbances of consciousness has been evaluated. Protocol based on previous experiences in evaluation of unconsciousness patients was used. Forty-four patients died and thirty-five survived. In 46 patients cause of illness was intracerebral hemorrhage. In 44 of them the cause of hemorrhage was arterial hypertension and in two of them rupture of a-v malformation. The majority of patients actually 41 of them showed hemispheral localization of intracerebral hematoma and five subtentorial. Pontien hemorrhages was found in three and cerebellar in two patients. In majority of 24 patients with hemispheral localization of intracerebral hematoma who showed progressive deterioration of consciousness the signs of descendent transtentorial herniation were found. The symptoms of uncal herniation were rare. In three patients with subtentorial localization of intracerebral hematoma who died signs of upward transtentorial herniation were observed. In 16 patients with ischemic cerebrovascular accident who showed disturbances of the consciousness at the admittance or soon after, nine patients died and seven survived. The cause of their condition were great hemispheral, smaller brain stem ischemic lesion, or deterioration of consciousness was related to the somatic illness. Patients with great ischemic lesions showed similar course of consciousness deterioration as it was observed in patients with hemispherical intracerebral hematomas with difference that biphasic course of illness characterized with temporary stagnation or even slight improvement of patients condition and than secondary progression of deterioration was seen only in patients with intracerebral hematoma, probably because of secondary ischemic complications. Ten patients were admitted because of subarachnoidal and two of them because of intraventricular hemorrhage. Six of them died and four survived. These patients has rupture of great sacular aneurysm with fast development of high intracranial pressure. In two of them the cause of death was rerupture of aneurysm. Stuporous patient with hemispheral neoplasm showed development of descendent transtentorial herniation which was stopped by anti oedematous and corticosteroid therapy. Comatose patient with brisk response on oculocephalic stimulation and normal papillary light reflexes was suspected on intoxication rather than structural brain lesion. He recovered by diuretics and forced rehydratation. After becoming conscious barbiturate intoxication was confirmed. Three patients were admitted in coma because of poisoning with CO, two patients died. Two patients admitted in epileptic status showed late diencephalic state of coma and they survived after anti epileptics and antioedematous treatment.

[Seizure-free paroxysms in epilepsy and migraine].

Fourty epileptic and 66 migraine patients were examined. The differences in clinical features of headache paroxysms, consciousness disorders, psycho-sensory++, viscero-autonomic++ and affective spells were determined. The elements of confused consciousness, short-lived and local autonomic responses were characteristic of seizure-free epileptic attacks. Migrainous paroxysms were multiform and pronounced in terms of autonomic disorders, had lesser depth and incidence of consciousness disorders with longer lasting vaso-autonomic++ crises.

Predictors of outcome in prolonged posttraumatic disorders of consciousness and assessment of medication effects: A multicenter study.

OBJECTIVES: To develop predictive models of recovery from the vegetative state (VS) and minimally conscious state (MCS) after traumatic brain injury (TBI) and to gather preliminary evidence on the impact of various psychotropic medications on the recovery process to support future randomized controlled trials. Design Longitudinal observational cohort design, in which demographic information, injury and acute care history, neuroimaging data, and an initial Disability Rating Scale (DRS) score were collected at the time of study enrollment. Weekly follow-up data, consisting of DRS score, current psychoactive medications, and medical complications, were gathered until discharge from inpatient rehabilitation. SETTING: Seven acute inpatient rehabilitation facilities in the United States and Europe with specialized programs for treating patients in the VS and MCS. PARTICIPANTS: People with TBI (N=124) who were in the VS or MCS 4 to 16 weeks after injury. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: DRS score at 16 weeks after injury and time until commands were first followed (among those participants demonstrating no command following at study enrollment). Results DRS score at enrollment, time between injury and enrollment, and rate of DRS change during the first 2 weeks of poststudy observation were all highly predictive of both outcomes. No variables related to injury characteristics or lesions on neuroimaging were significant predictors. Of the psychoactive medications, amantadine hydrochloride was associated with greater recovery and dantrolene sodium was associated with less recovery, in terms of the DRS score at 16 weeks but not the time until commands were followed. More detailed analysis of the timing of functional improvement, with respect to the initiation of amantadine provided suggestive, but not definitive, evidence of the drug's causal role. CONCLUSIONS: These findings show the feasibility of improving outcome prediction from the VS and MCS using readily available clinical variables and provide suggestive evidence for the effects of amantadine and dantrolene, but these results require confirmation through randomized controlled trials.
