How Mental Health Affects the Brain?

Image
During the times of physical and mental stress , the adrenal glands produce excessive levels of cortisol, with some of it ending up in the brain . Good mental health is an an essential part of our overall wellbeing, but not that many years ago mental health issues were thought of by many as something that was all in the mind. And while we know now that the mind is as important for health as the body, back then saying something was all in your mind was simply another way of saying you were probably imagining it. Then for the discoveries scientists have made more recent years about the causes of mental health problems, including the biological processes in the brain that are affected when someone has a mental illness. They are so many types of mental illnesses, which alerts a person’s feelings, thoughts and behaviours of a person. ·         Anxiety ·         Panic disorder ·         Eating disorders ·         Bipolar disorder ·         Seasonal affective disorder ·         Schizophr

Do You Know About the Stem Cell Therapy for Alzheimer's?

Image
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

Does Head Injury Causes Brain Trauma?

Image
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 consciousness. Severe cases might lead to extended periods of cognitive state, coma, or perhaps de

Why A Myelinated Neuron Conducts Impulses Faster?

Image
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 send information and signals throughout

What you should know about stroke prevention?

Image
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 star

Is Parkinson’s disease Genetic?

Image
  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

Do you know what Neurofibromatosis is?

Image
Neurofibromatosis (NF) is a term that refers to a set of three diseases in which tumours develop in the nervous system. Neurofibromatosis type I, type II, and schwannomatosis are the three kinds of neurofibromatosis. Skin patches, freckles in the armpit and groin, little lumps between nerves, and scoliosis are also indications of Neurofibromatosis 1. Hearing loss, cataracts at an early age, balance issues, flesh-colored skin flaps, and muscle wasting are all possible symptoms of Neurofibromatosis 2. Pain in schwannomatosis can occur in a single site or over a large area of the body. In most cases, the tumours in NF are non-cancerous. A genetic mutation in oncogenes is the root of the problem. These can be passed down from one's parents or occur spontaneously in around half of the cases during early development. The three forms of NF are caused by various mutations. Neurofibromatoses are caused by the nervous system's supporting cells, not by the neurons themselves. Neurofibroma
