Neurology diagnoses and treats disorders of the nervous system, including the brain, spinal cord, and nerves, as well as thought and memory.

Once the acute storm has passed, the vascular neurologist’s focus shifts to preventing recurrence. The strategy depends entirely on the stroke mechanism. For “large artery atherosclerosis” (plaque), antiplatelet agents (Aspirin, Clopidogrel) and high-intensity statins are used to stabilize the vessel wall. Carotid Endarterectomy (surgery) or stenting may be needed for severe neck blockages.
For “cardioembolic” strokes (like Atrial Fibrillation), antiplatelets are useless. Anticoagulation (Warfarin or DOACs like Apixaban) is mandatory to prevent clot formation in the heart. For “cryptogenic” strokes where a PFO (hole in the heart) is found, closing the hole with a device is often recommended for younger patients.
Stroke is the second leading cause of dementia. Vascular Cognitive Impairment (VCI) encompasses a spectrum from mild deficits to full-blown vascular dementia. Unlike Alzheimer’s, which is a gradual slide, vascular dementia often progresses in a “stepwise” fashion—stable periods punctuated by sudden drops following small vascular events.
Long-term care involves aggressive management of vascular risk factors to prevent “silent” strokes that accumulate to worsen cognition. Cognitive rehabilitation and the use of cholinesterase inhibitors (Alzheimer’s drugs) may provide modest benefits, but prevention of further insults is the only proven disease-modifying strategy.
The scar tissue formed by a stroke (gliosis) is electrically irritable and can become a focus for seizures. Post-stroke epilepsy requires long-term management with antiepileptic drugs. The risk is highest in hemorrhagic strokes and those involving the cortex.
Spasticity is a delayed complication where muscles become stiff and tight due to the loss of inhibitory signals from the brain. It can lead to painful contractures and hygiene problems. Treatment involves physical therapy, oral muscle relaxants, and injections of Botulinum toxin (Botox) to locally paralyze the overactive muscles and improve limb function.
Post-stroke depression is not merely a reaction to disability; it is a biological result of damage to the brain’s mood-regulating circuits. It affects 30% of survivors and significantly hampers rehabilitation efforts. Selective Serotonin Reuptake Inhibitors (SSRIs) are the first-line treatment and may also have a beneficial effect on motor recovery.
Pseudobulbar Affect (PBA) is a distinct condition characterized by uncontrollable crying or laughing that is incongruent with the patient’s actual emotional state. It results from a disconnection between the frontal lobes (motor control of emotion) and the brainstem/cerebellum (reflexive emotion). It is treatable with specific medications (dextromethorphan/quinidine).
In cases of massive, devastating stroke where recovery is unlikely, vascular neurology transitions to palliative care. This involves complex decision-making regarding artificial nutrition (PEG tubes) and tracheostomy. The focus shifts from extending life to ensuring comfort and dignity.
Vascular neurologists guide families through the prognostication process, which is fraught with uncertainty. Understanding the patient’s prior values regarding quality of life vs. disability is paramount. Hospice care provides symptom management for end-stage cerebrovascular disease, ensuring a peaceful transition.

The risk is highest in the first year (especially the first few weeks); however, with strict adherence to medication and lifestyle changes, the risk can be reduced by up to 80%
You must be cleared by a doctor; stroke can affect vision, reaction time, and spatial awareness in ways you might not notice, making driving dangerous until recovered.
This is likely Pseudobulbar Affect, a “short circuit” in the emotional reflex pathways; it is a neurological symptom, not a sign that you are losing your mind or purely depressed.
Spasticity tends to be a chronic condition; while it can improve, it often requires lifelong stretching and management to prevent the muscles from permanently shortening (contracture).
The damage already done is usually permanent, but unlike Alzheimer’s, the progression can be stopped or significantly slowed by strictly controlling blood pressure and preventing new strokes.
Carotid endarterectomy (CEA) is a surgery that cleans out the carotid arteries. It helps prevent strokes. This surgery is often done on older adults. But,
