Alzheimerâ€™s diseaseÂ is a neurological disorder in which the death of brain cells causes memory loss and cognitive decline. Alzheimerâ€™s is the progressive disease beginning with mild memory loss possibly leading to loss of the ability to carry on a conversation and respond to the environment. It Involves parts of the brain that control thought, memory, and language. It can seriously affect a personâ€™s ability to carry out daily activities.
Any disorder happen at the body nervous system is called asÂ Neurological Disorders. Abnormalities in the brain, spinal cord or other nerves like Structural, biochemical or electrical can result as symptoms sometime. Neurological disorder symptoms might be loss of sensation, Poor Coordination, muscle weakness, paralysis, confusion, pain and altered levels of consciousness. Causes for the neurological disorder can be biochemical changes and sometimes can be physical injury to the brain, spinal cord, or nerves. But in some case the root cause canâ€™t be determined only effects are seen.
Traumatic brain injuryÂ (TBI) is sudden damage to the brain caused by a blow or jolt to the head. Common causes include car or motorcycle crashes, falls, sports injuries, and assaults. Injuries can range from mild concussions to severe permanent brain damage. TBI may require intensive care and life-saving surgery. Those who survive a brain injury can face lasting effects in their physical and mental abilities as well as emotions and personality. Most people who suffer moderate to severe TBI will need rehabilitation to recover and relearn skills.
NeuroinflammationÂ is inflammation of the nervous tissue. It may be initiated in response to a variety of cues, including infection, traumatic brain injury, toxic metabolites, or autoimmunity. In the central nervous system (CNS), including the brain and spinal cord, microglia are the resident innate immune cells that are activated in response to these cues. The CNS is typically an immunologically privileged site because peripheral immune cells are generally blocked by the bloodâ€“brain barrier (BBB), a specialized structure composed of astrocytes and endothelial cells.
The bodyâ€™s systema nervosum is formed from two parts. The central systema nervosumÂ (CNS)Â includes the brain and therefore the medulla spinalis. The peripheral systema nervosumÂ (PNS)Â connects the nerves running from the brain and medulla spinalis to the remainder of the body the arms and hands, legs and feet, internal organs, Mouth, eyes, ears, nose, and skin and even the joints. When nerves are damaged or destroyed and messages from the brain and medulla spinalis to the muscles, skin and other parts of the body canâ€™t be sending, Peripheral neuropathy occurs.Â Peripheral nervesÂ go from the brain and medulla spinalis to the arms, hands, legs, and feet. Numbness and pain in these areas may occur when damage happens.
