Neurological disorders embrace a broad spectrum of disease entities that affect the central, peripheral and autonomic parts of the nervous system such as the brain, spinal cord, and nerves. Neurological disorders are produced due to various pathophysiological conditions; these include genetic mutation, traumatic injury, infection, and other conditions due to the degeneration of nerve cells due to age. Perhaps the most prevalent and severe neurological disorder is stroke; the disease manifests when blood flow to a part of the brain is either completely or partially blocked, hence causing damage or death to cells in that part of the brain. Stroke is one of the significant causes of death and long-term disability in almost all parts of the world, and there are essentially two types of strokes namely: ischemic and hemorrhagic.
Ischemic stroke is defined as the obstruction or narrowing of an artery in the brain that cuts off oxygen to brain tissue. A hemorrhagic stroke occurs when a blood vessel in the brain bursts and starts bleeding into or around the brain. Both the types of stroke might cause permanent damage to the affected region of the brains if their locations are located in sensitive parts of the brain. The most effective way to lessen the effects of a stroke is prompt medical care.
Common symptoms and signs of a stroke are sudden weakness, numbness or paralysis of one side of the face, arm, or leg; sudden confusion, difficulty in speaking, or understanding speech; sudden trouble in seeing or double vision, or severe headache. The FAST acronym—Face, Arms, Speech, Time—is used to make people realize their symptoms fast and seek medical help early. Time is a very important factor because early treatment reduces brain damage and increases the chances of success of treatments such as thrombolytic therapy (clot-busting drugs) or mechanical thrombectomy for ischemic strokes.
The neurological conditions linked with stroke are vascular dementia, cerebral small vessel disease, and post-stroke epilepsy. Survivors of a stroke mostly experience neurological impairments; such impairments include dysfunction of the motor functions, speech, cognitive functions, and emotional disturbances. Recovery from a stroke is maximized through effective rehabilitation, such as by therapies that can enhance mobility, speech functions, and mental abilities.
The latest developments in the treatment of a stroke include state-of-the-art imaging techniques for promptly diagnosing strokes, robot-assisted rehabilitation for quicker recovery from the disease, and neuroprotective drugs designed to preserve the brain cells in the limited damage caused. Prevention of a stroke is also one of the main focuses of neurological research; such approaches include lifestyle changes, antihypertensive and cholesterol-reducing drugs, and surgery for those at the greatest risk.
They have been understanding their neurological disorders and the causes of stroke through continuous research and bringing new treatments and preventive measures toward better brain health and long-term recovery.
