Cognitive disorders in patients with deep disability after surgery on intracranial aneurysmal hemorrhage
The characteristics of cognitive impairment in patients with deep disability after surgery on intracranial aneurysmal hemorrhage almost aren’t identified.
Aim. To determine the state of cognitive functions in patients with severe disability after surgery on intracranial aneurysmal hemorrhage.
Methods. The study included 328 patients with intracranial aneurysmal hemorrhages. 257 patients underwent intracranial surgery - arterial aneurysm clipping, 71 patients are operated by endovascular method. Immediate responses to the treatment are assessed at the end of inpatient treatment and 6 months after discharge on a scale of consequences Glasgow (GOS). Late results of the treatment were assessed by the modified Rankin scale 2.5 years after surgery. Deep disability status of patients is considered for GOS-2 (persistent vegetative state) or 3 points (severe disability) and for Rankin - 4 (Moderately severe disability) or 5 points (Severe disability). Cognitive impairment and ability to communicate was assessed using the MMSE scale.
Result. Quality of life in patients with deep disability changed over time. Immediately after surgery the average score for the MMSE amounted to 10.3 points, 6 months – 13.6, 2.5 years – 21.8. Violation of a guide at the time and place was much pronounced almost the entire time of observation. The function of the perception of information 2.5 years after surgery fully recovered in 72 % of patients. Only in 6 months after surgery 100% of patients with deep disability were dysfunction of concentration and arithmetic. This function completely restored only 2.5 years after surgery in 28 % of patients. The largest number of patients who completely regenerated memory function was observed 2.5 years after surgery. After 2.5 years of observation in 12 % of patients was observed a complete regeneration of reading function. Realization of three-phase commands in most patients remained broken in all time of observation.
Conclusions. Despite the presence of significant neurological deficits and dependence on others, general condition of cognitive functions within 2.5 years after surgery in patients with deep disability after surgery on intracranial aneurysmal hemorrhage is improved. Patients with deep disability after surgery on intracranial aneurysmal hemorrhages it is observe violation of all cognitive functions measured on MMSE scale. The most problematic in terms of restoring is function of realization of three-phase command
