Artery of Percheron infarction: review of literature with a case report.

Background: Clinical features indicating an ischemic infarction in the territory of posterior cerebral circulation require a comprehensive radiologic examination, which is best achieved by a multi-modality imaging approach (computed tomography [CT], CT-perfusion, computed tomography angiography [CTA], magnetic resonance imaging [MRI] and diffusion weighted imaging [DWI]). The diagnosis of an acute ischemic infarction, where the damage of brain tissue may still be reversible, enables selection of appropriate treatment and contributes to a more favourable outcome. For these reasons it is essential to recognize common neurovascular variants in the territory of the posterior cerebral circulation, one of which is the artery of Percheron.

Depression predicts the pattern of cognitive impairment in early Parkinson's disease.

Objective: To estimate the pattern of cognitive impairment in early Parkinson's disease (PD) associated with depression. Also, the prediction of potentially relevant demographic/clinical factors in early PD on cognitive functioning was tested.

Method: The study comprised 80 consecutive early PD patients (16 with major depression (PDMD), 10 PD patients with dysthimic disorder (PDDD), and 54 nondepressed PD patients (PDND)).

Surgical treatment of epilepsy: our experiences with 34 children.

Surgical treatment of medically intractable epileptic fits in children is highly specialized, owing to the specific etiology of epilepsies in this age group and the epileptogenic property of the brain in childhood. In our series of 340 patients operated on for medically intractable epileptic seizures, there were 34 (10%) patients up to 15 years of age (the youngest was 2 years old; mean age was 11 years). This group of patients comprises four subgroups: 9 patients with temporal foci, 6 patients with extratemporal foci, 16 patients with infantile hemiplegia and epilepsy, and 3 patients with epilepsia partialis continua (Kozhevnikov's disease).

Why are so few patients operated on for epilepsy? A Yugoslavian perspective.

A detailed review of the literature is provided which documents the discrepancy between the number of potential candidates for epilepsy surgery and the number actually operated on. Against a historical background, the limitations of understanding and of diagnostic tests are evaluated together with a careful review of long term surgical results, including those of the author.
