Neurologists play a critical role in the acute management and long-term care of patients who have had a stroke. They evaluate the type and severity of the stroke, determine appropriate interventions such as medication or clot-busting treatments, and provide guidance on stroke prevention strategies. Common symptoms of stroke include severe headache with no known cause, trouble with vision, such as blurred or double vision, dizziness or loss of balance and coordination, confusion or trouble understanding speech, Numbness or weakness on one side of the body, including the leg, and face drooping.

Parkinson's disease is a neurological condition that results in involuntary and uncontrolled movements, including tremors, muscle stiffness, and challenges with balance and coordination. These symptoms typically emerge slowly and progressively worsen as the disease advances. As the condition progresses further, individuals may experience difficulties with walking and speech.

Alzheimer's disease is the prevailing form of dementia and is characterized by a gradual deterioration of cognitive function. The initial stages often manifest as mild memory impairment and can eventually progress to a severe decline in the ability to engage in conversations and interact with the surroundings. Alzheimer's primarily affects the regions of the brain responsible for thinking, memory, and language.

Hemiplegia is paralysis of the muscles of the lower face, arm, and leg on one side of the body. In addition to motor problems other losses may occur eg. sensation, memory, cognition. The most common cause of hemiplegia is stroke, which damages the corticospinal tracts in one hemisphere of the brain.Hemiplegia can be temporary or permanent, relating to the severity and location of the stroke. A neurologist plays a crucial role in diagnosing, treating, and managing hemiplegia by assessing the underlying neurological causes, prescribing appropriate medications or therapies, and providing long-term care.
