Ischaemic Stroke: Treatment, Rehabilitation and Recovery
Ischaemic stroke is by far the most common type of stroke, accounting for about 85% of cases. It occurs when an artery supplying the brain is blocked, most often by a clot from the heart or from a narrowed, hardened artery, or by disease of small vessels deep in the brain. This article is part of our main guide, Stroke rehabilitation.
Emergency treatment: every minute counts
In eligible patients, clot-dissolving treatment (intravenous thrombolysis) and mechanical clot removal (thrombectomy) can restore blood flow. Their benefit depends strongly on time: the earlier treatment is given, the greater the chance of a good outcome [2, 3]. Decisions are made by the stroke team according to current guidelines [1].

Typical symptoms after ischaemic stroke
- Weakness on one side of the body (hemiparesis) or paralysis (hemiplegia)
- Speech and language problems (aphasia) or slurred speech
- Swallowing difficulty
- Visual field loss, balance and coordination problems
- Attention, memory and mood changes
The pattern depends on which artery was blocked. Middle cerebral artery strokes, for example, mainly affect the face and arm and, on the left side, language.
Rehabilitation after ischaemic stroke
Once the patient is stable, rehabilitation is planned by a multidisciplinary team [4]. It typically includes physiotherapy, occupational therapy, speech and swallowing therapy, and management of complications such as spasticity and shoulder pain. Intensive, task-specific practice is the core of motor recovery.
Preventing a second stroke
Secondary prevention is part of treatment: blood-pressure control, antiplatelet or anticoagulant medication as prescribed, cholesterol-lowering treatment, diabetes control, stopping smoking and regular physical activity [1].
The typical course of recovery
Recovery after ischaemic stroke (a stroke caused by a blocked artery) usually follows a recognisable pattern, although every patient is different. In the first days, swelling around the damaged area settles and some functions may return quickly. The following weeks and months are a period of increased brain plasticity (the brain’s ability to reorganise and form new connections), when targeted therapy has the greatest effect. Improvement then tends to slow, but practice can still bring gains in the chronic phase (more than six months after the stroke). Recovery is rarely a straight line: good weeks and slower weeks are common.
How recovery is assessed
The PM&R physician and the team examine movement, muscle tone, sensation, balance, walking, hand function, swallowing, speech, thinking and mood. Brain imaging (CT or MRI) shows where and how large the damaged area is, which helps with planning but does not by itself predict the outcome. Repeated measurements with standard scales show whether the programme is working and when goals need to change.
Treatment options in general terms
Rehabilitation combines repetitive, task-specific practice with exercise for strength, fitness and balance; occupational therapy for daily activities; speech, swallowing and cognitive therapy; and treatment of complications such as spasticity (muscle tightness), shoulder pain or low mood. In selected patients, supportive methods such as electrical stimulation or robot-assisted training may be added to active therapy. Secondary prevention, meaning control of blood pressure, cholesterol, blood sugar and heart rhythm together with the medicines prescribed by the treating physicians, continues for life.
What families can do
- Help the patient follow the home exercise programme and keep a simple diary of progress
- Make sure medicines are taken as prescribed and appointments are kept
- Encourage healthy eating, no smoking and regular activity
- Learn the warning signs of a new stroke
When to see your physical medicine and rehabilitation specialist
After acute hospital care, the rehabilitation process is best led and advised by a physician specialised in physical medicine and rehabilitation (PM&R, also called physiatry). At home, too, it is worth consulting a PM&R specialist, who examines the patient, sets goals and guides therapy and supportive treatments together with the physiotherapist and the wider team. Ask for a review if:
- function is getting worse instead of better, or progress has stalled for several weeks
- new pain, stiffness, swelling or falls appear
- mood, sleep, swallowing or bladder control change
- you are wondering whether a robotic or other advanced therapy might be suitable
Whether robotic or other advanced therapies are suitable is decided by a PM&R specialist focused on neurorehabilitation. Prof. Dr. Engin Çakar works in this field and can be consulted online or in person; otherwise, consult a PM&R specialist near you.
Call emergency services immediately for sudden new weakness, facial drooping, difficulty speaking, a severe headache or loss of consciousness: these can be signs of a new stroke.
Frequently asked questions
Is ischaemic stroke less serious than haemorrhagic stroke? Severity depends on the size and location of the affected area, not only on the type. Both types range from mild to severe.
How long does recovery take? Most improvement occurs in the first three to six months, but progress can continue with ongoing therapy.
Can a patient who missed emergency treatment still recover? Yes. Rehabilitation remains the main path to regaining function for all patients.
Is it safe to exercise after an ischaemic stroke? Yes, when the exercise is chosen and progressed according to the patient’s heart and blood pressure condition. Your physical medicine and rehabilitation specialist and the physiotherapist plan the type and intensity.
Will the patient need a walking aid permanently? Not necessarily. Aids are often used for safety during recovery and are reviewed as balance and strength change.
