Sensory stimulation therapy (SST) is an experimental therapy that aims to use neural plasticity mechanisms to aid in the recovery of somatosensory function after stroke or cognitive ageing. Stroke and cognitive ageing are well known sources of cognitive loss, the former by neuronal death , the latter by weakening of neural connections .
For example, a stroke affecting the right parietal lobe of the brain can lead to neglect for the left side of the visual field, causing a patient with neglect to behave as if the left side of sensory space is nonexistent (although they can still turn left). In an extreme case, a patient with neglect might fail to eat the food on the left half ...
Pain associated with Dejerine–Roussy syndrome is sometimes coupled with anosognosia or somatoparaphrenia which causes a patient having undergone a right-parietal, or right-sided stroke to deny any paralysis of the left side when indeed there is, or deny the paralyzed limb(s) belong to them. Although debatable, these symptoms are rare and ...
Extinction to double simultaneous stimulation is not only attributed to a primary sensory deficit since these patients are aware of contralateral stimuli presented individually. Attentional Deficit Hyperactivity Disorder (ADHD) is more focused on as a role of abnormal sensory processing of contralesional input. [ 7 ]
There are a wide variety of symptoms that have been found to be associated with sensory overload. These symptoms can occur in both children and adults. Some of these symptoms are: Irritability "Shutting down," or refusing to participate in activities and interact with others; Over-sensitivity to touch, movement, sights, or sounds
Unlike many effects of stroke, where the clinician is able to judge the particular area of the brain that a stroke has injured by certain signs or symptoms, the causation of apraxia is less clear. A common theory is that the part of the brain that contains information for previously learned skilled motor activities has been either lost or ...
Symptoms of a mild brain injury include headaches, confusions, tinnitus, fatigue, changes in sleep patterns, mood or behavior. Other symptoms include trouble with memory, concentration, attention or thinking. [3] Mental fatigue is a common debilitating experience and may not be linked by the patient to the original (minor) incident.
The most common stimulation related side effect at 1 year following implantation are hoarseness in 28% and paraesthesias in the throat-chin region in 12%. [70] At the third year the rate of stimulation related adverse effects decreased substantially with shortness of breath being the most common and occurring in 3.2%. [70]
