The risk of a second stroke is highest in the weeks and months right after the first one, with recurrence rates reaching up to 17% within 90 days. What you do (and don’t do) during this window has a real impact on whether you recover well or face setbacks. Here are the most important things to avoid after a stroke.
Stopping Medications on Your Own
This is one of the most dangerous mistakes a stroke survivor can make. Stroke survivors who discontinued their cholesterol-lowering medication within three to six months after a first ischemic stroke had a 42% higher risk of a recurrent stroke within one year compared to those who stayed on it. The actual recurrence rate was 6.2% for people who stopped versus 4.4% for those who kept taking it.
Blood thinners, blood pressure medications, and cholesterol-lowering drugs are all commonly prescribed after a stroke to prevent a second one. Side effects can be frustrating, and it’s tempting to stop taking pills once you feel better. But “feeling better” doesn’t mean the underlying risk factors are gone. If a medication is causing problems, talk to your care team about switching rather than quietly stopping.
Ignoring Blood Pressure
High blood pressure is the single biggest modifiable risk factor for both first and recurrent strokes. After a stroke, keeping your systolic blood pressure (the top number) below 140 mmHg is a common long-term target, though your specific goal may vary depending on whether you had a clot-based or bleeding-based stroke and what treatments you received.
This means you shouldn’t treat blood pressure monitoring as something that only happens at the doctor’s office. Home monitoring gives you and your care team a much clearer picture of how well your medications are working day to day. Sodium plays a direct role here: keeping sodium intake under 2 grams per day helps lower blood pressure, but most people far exceed that. In one large study, only 7% of participants were hitting that target before intervention.
Skipping Rehabilitation or Giving Up Too Early
After a stroke, many people naturally stop using the affected arm, hand, or leg because movements feel difficult or impossible. Over time, this creates a cycle called “learned non-use,” where the brain progressively suppresses motor pathways to the weakened side. The less you use it, the worse it gets, not because the damage is spreading but because your brain is learning to ignore that limb. People can start to believe they’re less capable than they actually are, which leads them to stop trying activities they could still manage with practice.
Rehabilitation works by pushing back against this process, forcing the brain to rebuild connections through repetitive, structured practice. Quitting therapy early or skipping sessions undermines the window when your brain is most ready to rewire. Even when progress feels painfully slow, consistent effort during rehab translates into better long-term function.
Letting Depression Go Untreated
Depression after a stroke is extremely common, affecting roughly half or more of all survivors. It’s not just a mood issue. Depression saps the motivation and energy you need for rehabilitation, and research shows that people whose depression persists tend to have worse functional outcomes than those whose depression is identified and treated. In one inpatient study, patients who recovered from depression had significantly better scores on measures of daily function compared to those whose depression continued unchecked.
Post-stroke depression doesn’t always look like sadness. It can show up as irritability, loss of interest in rehab, withdrawal from family, or persistent fatigue that goes beyond what the stroke itself would explain. Many survivors and families write these symptoms off as a natural response to a difficult situation, but they’re treatable and worth addressing directly.
Driving Too Soon
Getting behind the wheel too early is a common and dangerous mistake. A stroke can impair reaction time, visual processing, attention, and the ability to judge distances, even when you feel relatively normal at home. There’s no universal waiting period because strokes vary so much in size, location, and severity. The National Highway Traffic Safety Administration recommends that stroke survivors undergo a comprehensive driving evaluation by a trained rehabilitation specialist before returning to the road.
If your stroke involved a seizure, the timeline is stricter: most states require at least six months seizure-free, with a positive recommendation from your treating clinician, before you can legally drive again. Your neurologist or rehabilitation team can refer you for a formal driving assessment when the time is right.
Ignoring Fall Hazards at Home
Falls are one of the most common complications after a stroke. Balance, coordination, and spatial awareness are often impaired, and the home environment that felt perfectly safe before can become a minefield. Indoor tripping hazards like loose rugs, electrical cords, clutter in walkways, and poor lighting increase the likelihood of falling by about 25%. Outdoors, uneven sidewalks and obstacles are the biggest culprits.
A simple walkthrough of your home can make a real difference. Remove loose carpets or tape them down. Clear pathways between rooms. Make sure hallways and stairways are well lit, especially at night. Install grab bars in the bathroom. Broken or unstable furniture should be repaired or removed. These changes are inexpensive and can prevent a fall that could set recovery back by weeks or months.
Leaving Sleep Apnea Untreated
Between 50% and 70% of stroke patients have obstructive sleep apnea, yet it often goes undiagnosed. Sleep apnea causes repeated drops in blood oxygen and disruptions in blood flow to the brain during the night. In a recovering brain, this can directly compromise healing by reducing blood supply to already vulnerable tissue.
The practical effects are just as damaging. Untreated sleep apnea causes excessive daytime sleepiness, impaired concentration, and cognitive fog, all of which make it harder to participate meaningfully in rehabilitation. Stroke patients with sleep apnea have been shown to have longer hospital and rehab stays. If you or your family notice loud snoring, gasping during sleep, or unusual daytime fatigue, bring it up with your care team. Treatment can meaningfully improve both recovery speed and quality of life.
Dismissing New Symptoms
After a stroke, any sudden neurological change deserves immediate attention. About 1 in 3 people who experience a transient ischemic attack (sometimes called a mini-stroke) will eventually have a full stroke, with roughly half of those occurring within the first year. TIAs often happen hours or days before a major stroke, making them a critical warning sign rather than a minor event.
Sudden numbness on one side, confusion, trouble speaking, vision changes, or a severe unexplained headache should never be dismissed as “just a bad day” or chalked up to fatigue. The instinct to wait and see how things develop is understandable but risky. The treatments that prevent a full stroke work best when delivered quickly, and every minute counts.
