Alzheimer's disease (AD) may be a progressive neurodegenerative disease characterized memory loss and psychological feature impairment. It’s caused by conjugation failure and excessive accumulation of misfolded proteins. To date, most advanced clinical trials on specific AD-related pathways have unsuccessful largely thanks to an oversized variety of neurons lost within the brain of patients with AD. Somatic cell treatment has been thriving in AD animal models. Recent diagnosis studies on somatic cell medical care for AD have verified to be promising. Cell replacement therapies, like human embryonic stem cells or induced pluripotent stem cell–derived neural cells, have the potential to treat patients with AD, and human clinical trials square measure in progress during this regard. AD may be a progressive chronic unwellness that sometimes begins many years before identification. Therefore, a person's brain is severely broken by the time symptoms or signs seem and an oversized v...

Traumatic Brain Injury (TBI) may be a disruption within the traditional operate of the brain that may be caused by a blow, bump or jolt to the pinnacle, the pinnacle suddenly associate degreed violently touching associate degree object or once an object pierces the so and enters brain tissue. Observant one in all the subsequent clinical signs constitute alteration within the traditional brain function:          Loss of or weakened consciousness           Loss of memory for events before or when the event (amnesia)           Focal neurologic deficits like muscle weakness, loss of vision, amendment in speech           Alteration in a psychological state like disorientation, slow thinking or issue concentrating Symptoms of a TBI are delicate, moderate, or severe, counting on the extent of injury to the brain. Delicate cases might lead to a short amendment in psychological state or...

In a myelinated nerve fiber, the conduction of impulse is faster due to the presence of Myelin sheath and node of Ranvier.   As the rate of impulse conduction in a nervous system depends on the diameter of a nerve fiber and the presence or absence of myelin sheath.  Neurons with myelin sheath conduct impulse much faster than those without the presence of myelin. Schwann cells (or oligodendrocytes) are located at various regular intervals along the axons of the neuron. Between the areas of myelin are non-myelinated areas present, called as the nodes of Ranvier. Because fat or lipid molecules (myelin) acts as an insulator, a membrane coated with myelin does not conduct an impulse.  So, in a myelinated neuron, action potentials occur only along with the nodes and, therefore, impulses jump over the areas of myelin, going from node to node in a process called as saltatory conduction. Action potential velocity Brain cells are also called neurons which ...

A stroke occurs when the supply of blood to the brain is either interrupted or reduced. When this happens, the brain does not get enough oxygen or nutrients, and brain cells start to die. Nearly 800,000 people worldwide, have a stroke each year. That equates to about 1 person every 40 seconds. Strokes need to be diagnosed and treated as quickly as possible to minimize brain damage . Categories of Stroke: There are three main types of stroke: Ischemic stroke: This is the most common type of stroke. A blood clot prevents blood and oxygen from reaching the brain. Hemorrhagic stroke : This occurs when a weakened blood vessel ruptures and normally occur as a result of aneurysms or arteriovenous malformations (AVMs). Transient ischemic attacks: Also referred to as a mini-stroke, these occur after blood flow fails to reach part of the brain. Normal blood flow resumes after a short amount of time, and symptoms cease. How to prevent stroke?   Here are some simple ways to ...

  Parkinson’s disease may be a disorder of the nervous system. It is a progressive condition and causes widespread degeneration within the brain . Approximately 15% of individuals diagnosed with Parkinson’s disease have a known case history of the disorder. Biological interactions that produce to Parkinson’s are complex and not fully understood. Parkinson’s disease often begins with trembling or shaking of a part, especially when at rest. Symptoms are usually more pronounced across one-half the body, with many patients noticing it within the hand. It also can affect arms, legs, feet, and therefore the face. Not all patients experience every symptom within the early stages. Can Parents Pass Parkinson’s Disease to Their Kids? Children don't inherit Parkinson’s disease directly from their parents. However, a parent’s history of the disease makes it more likely that a toddler may experience it afterward in life. it's important to recollect that genes represent a probability...
