Prestroke dementia.

OBJECTIVE: To determine the frequency, associated factors and outcome of dementia previous to a stroke. DESIGN: Cross-sectional study of a cohort of 324 consecutive unselected stroke patients (mean age 70.9 years, range 20-98; 255 ischaemic, 46 haemorrhagic and 25 indefinite). METHODS: Cognitive and functional status prior to stroke were assessed by means of an interview to a relative, a short version of the Informant Questionnaire on Cognitive Decline in the Elderly and the Barthel Index. The DSM-III-R criteria were used to establish the diagnosis of prestroke dementia. Clinical and CT features of patients with and without prestroke dementia were compared. RESULTS: Forty-nine patients (15%) were demented before stroke; they were significantly older, less well educated, they had more frequently female gender, prior cerebrovascular disease, cerebral and medial temporal lobe atrophy and leukoaraiosis in the CT scan, and they had a higher mortality rate. Female sex (OR 3.7, CI 95% 1.2-12), low education (OR 2.1, CI 95% 1.1-4.2), previous stroke (OR 3.6, CI 95% 1.2-11), and cerebral atrophy (OR 3.8, CI 95% 1.7-8.3) were independently associated with prestroke dementia in the logistic regression analysis. CONCLUSIONS: Fifteen percent of stroke patients have prestroke dementia and they have a worse outcome. Factors associated with prestroke dementia are reminiscent both of degenerative and vascular brain pathology.

Poststroke dementia : clinical features and risk factors.

BACKGROUND AND PURPOSE: The goal of the present study was to examine a series of putative risk factors of poststroke dementia (PSD), especially those factors usually associated with cerebrovascular disease and degenerative dementia, in a series of 251 consecutive unselected stroke patients. METHODS: A standard protocol was prospectively applied at admission and 3 months after stroke; this protocol included clinical, functional, and cognitive assessments, hemogram and serum biochemistry, ECG and CT exams, apolipoprotein E and angiotensin-converting enzyme genotype, and neuropsychological examination. After a neuropsychological examination and an interview with a relative, the following diagnostic criteria were used: the Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV for dementia after stroke, DSM-III-R for previous dementia and dementia stage, and Association Internationale pour la Recherche et l'Enseignement en Neurologie (NINDS-AIREN) for vascular dementia. RESULTS: Seventy-five cases (30%) demonstrated dementia at 3-month follow up; 25 of them (10%) had demonstrated dementia before the stroke. Dementia was unrelated to type (ischemic/hemorrhagic) or location of stroke, vascular factors (hypertension, diabetes, ischemic heart disease, or hypercholesterolemia), apolipoprotein E or angiotensin-converting enzyme genotype, and serum homocysteine. Age (odds ratio [OR] 1.1, 95% CI 1.03 to 1.2), previous nephropathy (OR 6.1, 95% CI 1.5 to 24.3), atrial fibrillation (OR 4.4, 95% CI 1. 4 to 13.9), low Canadian Neurological Scale score at discharge (OR 0. 5, 95% CI 0.4 to 0.6), and previous mental decline assessed by the shortened Spanish version of the Informant Questionnaire on Cognitive Decline in the Elderly (SS-IQCODE; OR 1.2, 95% CI 1.1 to 1. 4) were the correlates of dementia in logistic regression analyses. The same risks factors were found when cases with previous dementia and with hemorrhagic stroke were excluded. CONCLUSIONS: Dementia is frequent after ischemic or hemorrhagic stroke. Age, nephropathy, atrial fibrillation, previous mental decline, and stroke severity independently contribute to the risk.

[Findings using magnetic resonance in a patient with non-traumatic anosmia].

INTRODUCTION: The presence of alterations in the neuroimaging in patients with anosmia without traumatic antecedents is not frequent. CASE REPORT: Male aged 38 who came to surgery after having suffered, 6 months earlier, for 1 week, a picture of intense, oppressive holocranial headache, accompanied by fever. Associated with this, an acute complete anosmia also began and persisted up to the moment the patient came for consultation. It was not associated with any infection of the respiratory tract, there was no history of cranial trauma, no ingestion of medicines nor toxins, nor had he been exposed to toxic products. The exploration to which he was submitted only showed an anosmia and was otherwise found to be normal. Cranial MRI showed signal alterations in both lower (orbitary) convolutions of the frontal lobes, in the anterior region of the right temporal lobe and in both olfactory nerves. Tests for HIV serology, parotiditis, hepatitis B and C virus, HSV, VZV, Mycoplasma pneumoniae and lues were negative. The acute onset of the anosmia in midst of a picture of febricula and headaches made us suspect the presence of an infectious aetiology, and the alterations found in the neuroimaging could be due to post encephalic lesions, with a special predilection for olfactory areas. CONCLUSIONS: 1. MRI plays a fundamental role in the topographic and aetiological evaluation of olfactory dysfunctions of a central origin; 2. Affectation of the central olfactory passages of an infectious aetiology in a non HIV patient and with neuroimaging findings is a rare complication.
