Brain monitoring devices identify and measure any abnormality in the functioning of the brain cells (neurons) that are linked with neurological disorders such as Alzheimer’s, Parkinson’s, epilepsy, dementia, multiple sclerosis, sleep disorder, and brain tumor. Monitoring brain functions such as blood flow, pressure surrounding the brain, electrical and neural activity, gravity adjoining the brain, cerebral oxygen capacity, tumor, traumatic brain injury, and other conditions can aid in preventing serious consequences. Increasing stress level and rapid onset of aging are major factors increasing uptake of preemptive monitoring to detect neurological conditions. Treating a brain disease incurs major cost, with risk for death due to high complexity in certain neurological condition. Therefore, early diagnosis and regular health check is recommended by healthcare service providers and practitioners.
