A stroke occurs when the brain is deprived of sufficient oxygen and nutrients.
A stroke is a cerebrovascular disease which causes a blood clot or a bleed in the brain which may lead to permanent neurological damage and complications. Because the brain needs a never ending supply of oxygen and nutrients to work efficiently, even starvation of the blood supply for a short period of time can cause problems as the brain cells begin to die. Often resulting in paralysis and sometimes death.
The part of the brain which regulates sensation is known as the 'thalamus', which is responsible for relaying 98% of sensory input. So, it stands to reason that the vast majority of thalamic stroke patients will often display numbness and sensory issues.
Successful recovery from a stroke will often involve specific therapies and support systems, including multi-discipline therapies which will help with speech impairment, movement and coordination, tiredness, daily activities including reading and writing, mood swings, lack of concentration and memory problems.
Therapy, such as 'sensory retraining' often includes the use of tactile sensory products, such as the Samboards sensory touch pad, to help regain sensation after a stroke.
