A stroke occurs when blood flow to part of the brain is interrupted or bleeding damages brain tissue. Lasting effects can involve movement, speech, thinking and daily activities. New stroke symptoms require emergency care; HBOT is not a substitute for time-sensitive stroke treatment.
Research has explored HBOT during recovery from an earlier stroke. A 2013 randomized study reported improvements after treatment in people with persistent deficits, compared with a period without treatment. The study did not use a sham-treatment control, which limits conclusions about how much improvement was specifically due to HBOT. This remains an investigational approach to recovery and should complement, rather than displace, rehabilitation and measures to reduce further stroke risk.
A progressive brain disorder that gradually impairs memory, thinking and the ability to manage daily life.
Poor arterial blood flow can cause hard-to-heal wounds or sudden loss of retinal circulation.
A neurodevelopmental condition involving differences in communication, sensory processing and behaviour.
A rare condition in which small blood vessels calcify and clot, causing painful skin wounds and tissue damage.
Delayed brain tissue injury after radiation therapy that can cause swelling and neurological symptoms.
A complex illness causing severe fatigue, reduced activity tolerance and worsening symptoms after exertion.
A chronic pain disorder causing severe pain, sensitivity and changes in a limb after injury or surgery.
COVID-19 is a viral illness; Long COVID involves persistent or recurring symptoms after the acute infection.
Severe trauma can damage muscle and circulation, causing swelling, tissue injury and compartment syndrome.
A neurological disorder characterized by a tendency to have recurrent, unprovoked seizures.
A rare disorder causing episodes of burning pain, redness and warmth, usually in the feet or hands.
Neurological headache disorders that can cause severe pain, nausea, sensory sensitivity and repeated attacks.
