Purpose:
To study relationships between fatigue and objective and subjective cognitive functioning, mood and comorbidity in the long term after perimesencephalic subarachnoid haemorrhage (PM-SAH).
Methods:
Cross-sectional study. Objective cognitive functioning was measured with: Trail Making Test; Symbol Substitution; D2; Verbal and Semantic Fluency; Tower Test; Digit Span; 15-Words Test; Rey Complex Figure. Subjective cognitive functioning: Cognitive Failure Questionnaire. Fatigue: Fatigue Severity Scale. Mood: Hospital Anxiety and Depression Scale.
Results:
Forty-six patients, mean age 50.4 (SD = 9.4), mean time after PM-SAH 4.7 (SD = 1.6) years participated. Patients with fatigue (33%) had significantly lower scores than patients without fatigue on most objective cognitive functioning tests (p < 0.05). Fatigue score was significantly associated with subjective and objective cognitive functioning, mood and comorbidity. After adjustment for mood and comorbidity, fatigue remained associated with attention and executive functioning.
Conclusions:
This study supports our previous findings that a third of patients with PM-SAH experience fatigue and problems of cognitive functioning, also in the long term. Future research should investigate whether these patients would benefit from long-term follow-up and/or cognitive rehabilitation programmes. Implications for Rehabilitation Consequences for patients with PM-SAH are underestimated. One in every three patients suffered from fatigue in the long term after onset of PM-SAH. Patients with PM-SAH should be screened for problems of cognitive functioning, fatigue and mood in outpatient clinic just as patients with aneurysmal SAH.

Amnesia
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
Anterograde...
