Stroke: A few reminders
A stroke is a condition affecting the central nervous system (brain, brainstem, cerebellum, spinal cord). It involves a disruption of blood flow to a specific area of the brain, frequently resulting in neurological deficits. 140,000 new cases per year in FranceThis is the leading cause of disability.
There are two types of strokes: hemorrhagic strokes (approximately 20%) and ischemic strokes (approximately 80%).
Strokes due to cerebral hemorrhage are mainly caused by a ruptured aneurysm, an arteriovenous malformation (usually in young people) or a sudden increase in blood pressure (usually in older people).
Strokes caused by cerebral ischemia have various etiologies: the most common is atherosclerosis/thrombus of the aorta (with clot migrating to the brain), or of the carotid artery or intracerebral arteries (middle cerebral or sylvian, anterior cerebral, posterior cerebral, basilar artery). The origin can also be cardioembolic (cardiac arrhythmia, myocardial infarction, heart failure), tumoral, etc.
Paralysis or numbness of the face, a limb or one side, speech or comprehension difficulties, sudden change in vision, sudden loss of balance, sudden and intense headaches are suggestive signs of a suspected stroke and require an emergency call to 15.
What are the clinical presentations of a stroke?
There are as many clinical presentations as there are strokes.
The brain lesion causes contralateral hemiplegia or hemiparesis to the injured hemisphere (right hemisphere lesion: left hemiplegia and vice versa).
This hemiplegia/paresis may sometimes be transient and spontaneously reversible (as in the case of Transient Ischemic Attacks: TIA).
The clinical presentation involves sensory and/or motor impairment of all or part of one side of the body. This corresponds to paralysis/paresis of the limb(s), which may be accompanied by altered muscle tone (specific to these lesions of the so-called "pyramidal" pathway): flaccidity/spasticity.
These deficiencies can have a daily functional impact on walking, balance, grasping, washing, dressing, and eating.
They can be associated with alterations in cognitive functions: aphasia (language and communication: written, oral), apraxia (gestural sequence), hemineglect, visual field (homonymous hemianopsia for example), memory (memory disorders), attention, concentration, fatigue…
Stroke: What rehabilitation is available?
La neurological rehabilitation Recovery after a stroke is often slow, prolonged, and incomplete. On a cerebral level, it occurs through mechanisms of brain plasticity (cerebral remodeling and reorganization). Rehabilitation professionals indirectly "guide" this plasticity by stimulating the patient's motor, sensory, and cognitive abilities.
The Allyane method is a valuable complement to motor rehabilitation. It integrates the patient's proprioceptive sensations into motor imagery (a specific form of mental imagery), coupled with low-frequency sounds. These specific sounds, generated by a medical device, increase the emission of alpha brain waves, hyperactivating the motor areas. Through this process, the method aims to correct or recreate the visualization of the movement.
