This document provides an overview of various vascular lesions of the brain. It discusses arteriovenous malformations (AVMs), dural arteriovenous fistulas, carotid-cavernous fistulas, cavernomas, capillary telangiectasias, venous angiomas, aneurysms, and other conditions. For each type of lesion, it describes characteristics, imaging appearance, clinical presentation, and treatment options. Magnetic resonance imaging and cerebral angiography are important diagnostic tools. Treatment may involve surgery, endovascular procedures, or radiosurgery depending on the specific lesion.
This document summarizes sonothrombolysis as an adjuvant treatment for acute ischemic stroke. It discusses how ultrasound enhances the lytic effects of tPA to improve recanalization rates. Sonothrombolysis delivers ultrasound through acoustic windows in the skull to the occlusion site. Ultrasound may improve clot lysis mechanically and by promoting tPA activity. Two phase III trials, CLOTBUST and CLOTBUST-ER, found sonothrombolysis had a good safety profile but no additional clinical benefit over tPA alone. Current guidelines do not recommend sonothrombolysis outside of clinical trials due to lack of proven efficacy.
Subarachnoid hemorrhage a major complication ,this presentation can help you understand the disease, the signs & symptoms and give you the diagnostic feature ,I hope you well enjoy studying it ... Good luck :)
This document provides an overview of orthostatic tremor. It describes it as a rare movement disorder characterized by a fast tremor of the legs that occurs primarily when standing and is relieved by sitting or walking. The tremor has a frequency of 13-18 Hz. It most often affects women over 60 years of age and can progress to involve other parts of the body over time. Diagnosis involves clinical examination finding the high frequency tremor and electromyography showing oscillations in the 13-18 Hz range. Treatment options include non-pharmacological measures as well as deep brain and spinal cord stimulation.

This document provides an overview of the general approach and examination for neurological causes of vision loss. It discusses evaluating for monocular versus binocular visual loss and whether the loss is transient or persistent. The examination involves assessing visual acuity, color vision, visual fields, pupils, eye examination, and funduscopy. For transient monocular visual loss, causes like emboli, vasculitis, and giant cell arteritis are discussed. Persistent monocular loss localizes to the eye or optic nerve. Binocular transient loss is often due to migraines or TIAs, while persistent binocular loss results from retrochiasmal strokes. Progressive vision loss indicates a compressive lesion. Specific conditions like optic neuritis, NA
Cortical dysplasia is a malformation of cortical development caused by abnormal neuronal migration or organization during brain development. It can cause intractable epilepsy and neurodevelopmental disorders like autism. The lecture discusses normal brain development and corticogenesis. It then covers specific malformations including focal cortical dysplasia, describing their histopathology and clinical correlates. Recent research suggests focal disruptions of cortical layering found in children with autism may represent early cortical dysplasia, providing insight into a potential cause of autism.
