How Mental Health Affects the Brain?



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
·         Schizophrenia


The brain and mental illness:


What will happen in the brain when someone has a mental health? We are still having such a lot to learn about the relation between these two things, but nowadays it’s thought that mental health problems are linked with changes in neurotransmitters, which cause problems with the communications between neurons, as well as changes in the brain’s structure and function.
Take the depression, for instance a mental health issue that affects around one in 10 of us at some point during our lives .When someone is affected by depression, brain typically has high levels of chemicals called cortisol.
During the time of physical and mental stress, the adrenal glands produce excessive levels of cortisol, with some of it ending up in the brain. But when the brain is exposed to high levels of cortisol in the long term it can change your brain chemistry, which then triggers symptoms of depression.
However changes in neurotransmitters other than serotonin can also play a part in depression, and other antidepressant medications include serotonin-norepinephrine reuptake inhibitors, which alter the amounts of serotonin and norepinephrine in the brain, and norepinephrine-dopamine reuptake inhibitors, which increase brain levels of norepinephrine and dopamine.

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...

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 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...
