For those whose lives have been touched by neurological disorders, you know how challenging it can be at times. Neurological disorders affect the human brain or central nervous system and have a variety of symptoms that range from extremely debilitating to very subtle. Hopefully, as technology advances we are able to find answers to many of the questions surrounding these abnormalities. Until then, it is best to educate ourselves so that we have a better understanding of the symptoms and classifications that science has uncovered.
Neurology and neuropsychology are the specialties by which neurological disorders are studied and examined. Through a neurological examination, patients are thoroughly tested by either a screening tool or an investigative tool to assess the motor responses and sensory neurons.
The way neurological disorders are categorized is based on either the type of dysfunction the individual is facing, the main area of the brain affected, or the cause of the disorder. Some categories you may have heard of include amnesia, movement disorders such Parkinson's disease, and multiple sclerosis. While some disorders are more common than others, some are extremely rare with very little understanding behind both the causes and the symptoms. Neurological disorders are classified based on certain criteria and oftentimes symptoms can cover several categories and which make them difficult to classify.
When looking at the brain within the body, we see that there are several layers of protection to prevent damage to neural networks. The skull, membranes, and blood-brain barrier all are in place to prevent electrochemical and structural impairment. In the event that these systems are compromised, neurons and the neural networks become exposed to damage. It is very likely that problems then occur once these systems are disrupted. Symptoms are caused by neurological disorders stemming from electrical abnormalities, biochemical disorders, or structural irregularities. Some of which include paralysis, difficulty with coordination, or even seizures. Once a diagnosis is made physicians are likely to recommend preventative measures such as therapy, pain management, or neurorehabilitation. Some cases may even require neurosurgery.
Researchers are constantly finding new ways to treat neurological disorders, but until we fully understand the lifecycle of neurons and the genetic, environmental, and immunological functions of the brain, we will constantly battle the debilitating affects they have on the patient's life.
