MRI Parameters Of Alzheimer's Disease in an Arab Population of Wadi Ara, Israel

Magnetic resonance imaging (MRI) findings are reported from 15 individuals in an Arab–Israeli community who were diagnosed with Alzheimer's disease (AD). The quantitative parameters that were used for MRI analyses included gradings (0–3) and linear measurements of different brain structures. Generalized tissue loss was assessed by combined measurements of the ventricles (ventricular score, VS) and sulcal grading and width (SG, SW, respectively). Loss of brain tissue in specific regions of interest, eg, temporal lobes, basal ganglia, and midbrain, was evaluated by precise measurements. We observed abnormal tissue characteristics, expressed as high intensity foci in white matter on T2W sequences, as well as tissue loss, both generalized and focal. Most notable were changes involving the head of the caudate nuclei, the midbrain, and to a lesser degree, medial temporal structures.National Institute of Aging (UO1-AG17173); National Institute on Alcohol Abuse and Alcoholism (R37-AA07112, K05-AA00219); US Department of Veterans Affair

Duretovo krvarenje: rijetka komplikacija ishemijskog moždanog udara u području središnje moždane arterije - Prikaz slučaja

We report on an unusual case of brainstem Duret hemorrhage after ischemic stroke in the anterior circulation. The patient showed a clinical and neuroradiological picture of an acute and malignant middle cerebral artery infarct with increased intracranial pressure followed by a brainstem hemorrhage. The report suggests that the descending transtentorial herniation of any etiology might be complicated by a Duret hemorrhage.Opisuje se rijedak slučaj Duretova krvarenja moždanoga debla nakon ishemijskog moždanog udara u prednjem krvotoku. Bolesnik je pokazivao kliničku i neuroradiološku sliku akutnog i zloćudnog infarkta središnje moždane arterije uz povišen intrakranijski tlak, nakon čega je uslijedilo krvarenje u moždanom deblu. Ovaj prikaz ukazuje na to da se Duretovo krvarenje može pojaviti kao komplikacija kod silazne transtentorijske hernijacije bilo koje etiologije
