A neurological assessment may be appropriate for symptoms affecting the brain, spinal cord or nerves. These may include recurring headaches, dizziness or vertigo, seizures, memory changes, weakness, numbness, tremors or difficulties with movement, speech or balance. The need for assessment depends on the symptoms, their duration and the person's medical history. Sudden weakness, difficulty speaking, vision changes or loss of balance may indicate a stroke and require immediate emergency medical attention.

Neurological conditions vary in their causes, severity and course. Some are temporary or treatable, while others may require long-term management and monitoring. Symptoms alone may not establish the underlying cause. A clinical assessment helps identify possible explanations, determine whether further investigations are needed and guide decisions about treatment and follow-up.

Neurology involves evaluating and managing conditions affecting the brain, spinal cord, nerves and muscles. Treatment may include medication, monitoring, rehabilitation and other non-surgical approaches. Neurointervention involves catheter-based procedures guided by medical imaging to evaluate or treat selected conditions affecting blood vessels in the brain, neck or spine. The appropriate approach depends on the condition, investigation findings and individual clinical needs.

A neurointerventional procedure may be considered for selected conditions, including certain types of acute ischaemic stroke, brain aneurysms, arteriovenous malformations (AVMs) and narrowing of arteries supplying the brain. The decision depends on factors such as the condition being treated, imaging findings, symptoms, timing and the potential benefits and risks of the procedure. Depending on the diagnosis, medication, monitoring, surgery or other treatment options may also be considered. Not every patient requires an intervention.

No. Many neurological conditions can be managed with medication, monitoring, rehabilitation or other non-surgical approaches. Some conditions may require a procedure or surgery, depending on their nature, severity and associated risks. Treatment decisions are based on the clinical assessment and relevant investigation findings, with the available options considered for each individual.

Stroke is a medical emergency. It may occur when a blood vessel supplying the brain becomes blocked or when a blood vessel ruptures and causes bleeding. Warning signs can include sudden weakness or numbness, facial drooping, difficulty speaking, vision changes or loss of balance. Emergency assessment is essential because treatment options depend on the type of stroke, the time since symptoms began and other clinical findings. Selected patients with an ischaemic stroke may be eligible for clot-dissolving medication or mechanical thrombectomy. Do not wait for symptoms to improve before seeking emergency care.

Investigations depend on the symptoms, medical history and findings from the clinical examination. They may include blood tests, CT scans, MRI scans, nerve conduction studies, electromyography (EMG), electroencephalography (EEG) or specialised blood vessel imaging. Not every patient needs all these tests. The choice of investigation depends on the clinical question being assessed and whether the results may help guide diagnosis or treatment.

Some neurological conditions cannot be prevented, but managing certain risk factors may help reduce the risk of conditions such as stroke. Measures may include controlling blood pressure, diabetes and cholesterol, avoiding tobacco, staying physically active and following medical advice for existing health conditions. The relevance of these measures varies according to a person's health and risk factors. A healthcare professional can help identify appropriate preventive steps.

Rehabilitation may help address difficulties with movement, balance, speech, swallowing, memory or everyday activities following a neurological illness or injury. Depending on individual needs, it may involve physiotherapy, occupational therapy, speech and language therapy or cognitive rehabilitation. The rehabilitation plan and its duration depend on the condition, the functions affected and the person's progress. Follow-up helps assess changing needs and guide adjustments to the plan.
