Brain Diseases Common Causes, Symptoms and Treatments

Brain Diseases Common Causes, Symptoms and Treatments. The human brain may be a remarkable piece of kit . The National Library of drugs calls it “the center of the body. It controls thoughts, memory, speech and movement. It regulates the function of the many organs.” When your brain is healthy, it manages all those functions automatically.

Brain Diseases

The brain is amazingly complex, says Dr. Sarah Benish, a neurologist with University of Minnesota Physicians, adjunct professor of neurology at UM school of medicine and a fellow of the American Academy of Neurology. The brain comprises about 86 billion nerve cells, and there are quite a trillion connections among brain and nerve cells throughout the body, she says. Read More Trending Topic About Coronavirus

The Causes, Symptoms and Treatments for Common Brain Diseases

The brain is what makes us us. It gives us personality, allows us to speak and feel, gives us emotions. It’s remarkable that, for the bulk folks , it works quite well. However, when problems occur, the results are often devastating, the NLM adds. Brain and neurological diseases affect about 1 in 6 people and price quite a trillion dollars in annual treatment, consistent with the American Brain Foundation. Given the brain’s complexity, it’s not surprising that numerous things can fail . In fact, the National Institute of Neurological Disorders and Stroke supports research on quite 600 neurological diseases. Symptoms of brain disorder vary widely, counting on the disease in question.

Treatments, including medication, surgery and physical or physical therapy, can help many brain diseases, but not all. Prognoses also range across the spectrum – from curable to treatable, permanently disabling or maybe fatal. On the entire, neurology and brain diseases wont to be referred to as diseases that didn’t really have treatments,” Benish says. “Brain diseases are often highly complex, and tons of individuals think there are tons that can’t be treated, but there are tons of treatments out there.” Treatments, counting on the condition and severity, can include medication, surgery and gene therapy.

Brain Structure

The NINDS calls the brain “the assets of the physical body. Weighing 3 pounds, the brain is the seat of intelligence, interpreter of the senses, initiator of body movement and controller of behavior. The brain is split into three sections: the forebrain, midbrain and hindbrain. The forebrain, the most important and most highly developed part, comprises the cerebrum, which is reverse split the center into two halves, and a few other structures. The midbrain, located at the highest of the brain stem (the lower a part of the brain, where the medulla spinalis comes into the brain), is liable for some reflex actions and is involved in controlling eye and other voluntary movements.

The hindbrain includes the upper a part of the medulla spinalis , the brain stem and therefore the cerebellum. It controls vital functions, including breathing and pulse . It also helps with movement, including learned movements like playing a instrument or swinging a golf club. The main sort of nerve cell is named a neuron. “All sensations, movements, thoughts, memories and feelings are the results of signals that undergo neurons,” the NINDS writes. Made from a cell body, axons and dendrites, neurons communicate with each other by passing chemicals, called neurotransmitters (or neurochemicals), between their connections.

Types of Brain Diseases

The most common categories of brain disorder , consistent with the American Brain Foundation.

Autoimmune diseases. MS , or MS, may be a disease of the central systema nervosum during which the body’s system attacks myelin, the tissue that covers nerves. This interferes with neural communication between the brain and therefore the body. Symptoms include blurred vision, weakness within the arms and legs, speech problems, tremors and sometimes paralysis. There are treatments, but no cure. Other autoimmune brain diseases include:

  • Autoimmune encephalitis
  • Autoimmune-related epilepsy
  • Central systema nervosum vasculitis
  • Hashimoto’s encephalopathy

Autism and neural development diseases

The NBF defines autism spectrum disorders as “a group of developmental disorders distinguished by behaviors that range from mild to disabling. About one child in 68 is diagnosed with autism by the age of 8.” Markers of autism include social awkwardness, poor verbal and nonverbal communication, repetitive behaviors and obsessive interests and habits. Its causes aren’t known, though genetics and environmental factors are suspected. Other sorts of neurodevelopment disorders include hypoxic/ischemic encephalopathy (brain injury caused by oxygen deprivation to a newborn’s brain), spastic paralysis , developmental disorders and a spotlight deficit hyperactivity disorder, or ADHD. counting on the severity of the case, medical and behavioral therapies can help, especially if the disease is diagnosed early.

There are many sorts of dementia, including frontotemporal dementia, Lewy body dementia and vascular dementia, but Alzheimer’s disease is that the commonest and maybe the simplest known. Aging, genetics and lifestyle factors all play a task in dementia, though the precise causes are unclear. Symptoms of dementia include a progressive loss of cognitive and functional ability, resulting in a loss of independence. There are currently no effective treatments, but many trials are underway which will offer hope to patients and their families within the coming years. “Even before people have symptoms, there are changes in brain structure and chemistry” that suggest Alzheimer’s, Benish says. Numerous trials are currently looking to spot the disease as early as possible, before memory problems surface, and begin treatments then. “That is where the switch in research has been made,” she says.

Common brain diseases caused by an infection include meningitis and encephalitis. Meningitis is an infection within the lining round the brain or medulla spinalis . Encephalitis is an infection of the brain tissue. They often occur together and may cause neck stiffness, headache, fever and confusion. they will be fatal without antiviral treatment.

Movement disorders. Parkinson’s disease, ataxias, tremor, dystonia, tics and Tourette syndrome are samples of movement disorders that always reach an entire loss of function. they will cause tremors, slow and stiff movement, loss of balance, speech impairment and difficulty walking. Parkinson’s disease is caused by the loss of dopamine-producing brain cells. All movement disorders, the ABF says, “are complex disorders with genetic and environmental factors contributing to their cause.” Though no cure is understood , drug and physiotherapy treatments can help relieve some symptoms.

Neuromuscular diseases

These disorders attack peripheral nerves outside the brain and therefore the muscles they control. Amyotrophic lateral sclerosis, commonly mentioned as ALS or Lou Gehrig’s disease, is that the best known of those diseases – having taken the lives of Gehrig, of course, and, more recently, the scientist Hawking . It typically progresses rapidly and is ultimately fatal. it always doesn’t affect thinking and cognition, but the ABF says that recent studies suggest some ALS patients may develop memory and decision-making problems. There are treatments to slow ALS or help with symptoms, but there’s no cure. Other neuromuscular diseases include peripheral neuropathy (caused by diabetes, chemotherapy or genetics), Guillain-Barre syndrome and CIDP (chronic inflammatory demyelinating polyneuropathy), myasthenia and dystrophy .

Seizure disorders

Epilepsy and other seizure disorders affect about 3.4 million people, consistent with the Centers for Disease Control and Prevention. Seizures are caused by an interruption in brain activity, either due to illness, brain damage or other factors. along side epilepsy, other seizure disorders described by the ABF include mesial lobe epilepsy, post stroke/post concussive epilepsy and genetic and pediatric inherited epilepsy syndromes (such as Lennox-Gastaut, Dravet, West syndrome and juvenile myoclonic). they’ll be caused by genetic anomalies, but often the cause is unknown. Medical and surgical treatments can help about 70% of these with epilepsy, the ABF says.

Stroke and vascular diseases

Stroke is that the leading explanation for permanent disability in adults. An ischaemic stroke is when blood flow to the brain is impaired by a blocked vessel . A haemorrhagic stroke is when a vessel within the brain ruptures, causing bleeding into the brain. Both sorts of stroke kill brain tissue. Symptoms for both include sudden confusion, weakness within the arms or legs – especially on one side of the body – vision and speech impairment and sudden emotional control problems. Treatment depends on the sort of stroke.

For an ischaemic stroke , administering a blood-thinning drug called tPA within three hours of the stroke can hack the grume and restore blood flow before brain damage is just too extensive. “The brain isn’t excellent at healing after injury,” Benish says. “That’s why we attempt to treat stroke as quickly as possible, to revive oxygen and stop long lasting damage.” Surgery is usually necessary for haemorrhagic stroke . Other vascular diseases, which may limit blood supply to the brain, include vasculitis and fibromuscular dysplasia.


The CDC reported in 2019 that there have been approximately 2.87 million traumatic brain injuries within the U.S., including over 837,000 occurring among children, in 2014 – the foremost recent year statistics were available. Trauma, including concussion, are often mild or severe, and may cause anything from a light headache to confusion, loss of consciousness, convulsions and even death. Benish stresses the importance of head protection for everybody . “The specialise in preventing brain diseases has changed over the years to, favorite , prevent injury,” she says. “I tell my patients to avoid head trauma. Wear a helmet if you’re biking, rollerblading, skiing, things like that.

The brain doesn’t do alright with repetitive head traumas.” Chronic traumatic encephalopathy, or CTE, may be a progressive disease that’s been found in military veterans and in athletes, like football and hockey players, who experience repeated head trauma. It can cause amnesia , confusion, personality and behavior changes, balance and motor impairment and violence or suicide. Surgery and drugs can treat some sorts of brain trauma, and physical and behavioral rehab is additionally sometime effective.


Both benign and malignant tumors can put pressure on brain tissue or destroy tissue, causing problems within the body related to the world of the brain affected. Tumors can start within the brain or metastasize there from other organs. The ABF says the foremost common brain tumors are glioblastoma tumors, metastatic brain lesions, astrocytomas and meningiomas. Symptoms depend upon the dimensions and site of the tumor, but can include pain, headaches, seizures, nausea and vomiting, vision or hearing problems, behavioral and cognitive problems or motor and balance issues. Treatments may involve surgery, radiation, chemotherapy or a mixture of them. Newer and still-experimental treatments, including gene therapy and immunological therapy, show promise for future tumor treatment strategies.

Causes: The NINDS lists the subsequent known causes of brain disease:


Swelling within the brain could also be caused by infection, an autoimmune reaction or some unknown reason. Over time this will irritate and damage brain tissue. MS and vasculitis are two samples of inflammatory brain disorder . A traumatic brain injury may cause inflammation, also as direct damage to the brain.


Disruption of blood flow to the brain can cause the loss of brain cells, which may affect movement, speech and thinking.
Brain tumors. Tumors can continue tissues and nerves and affect brain function.


Some brain diseases like Tay-Sachs disease. Huntington’s chorea, muscular dystrophies and Wilson disease, are genetic. they’re typically diagnosed through a clinical exam case history and, in some case.


Of course symptoms vary widely counting on the precise condition. But the subsequent are some common physical and/or cognitive symptoms of a brain disorder.

Physical symptoms:
  • Changes in hearing, speech or vision
  • Paralysis
  • Seizures
  • Poor balance or dizziness
  • Headaches
  • Nausea and vomiting
  • Shakes and tremors
  • Weakness in arms or legs
  • Loss of sense of smell or taste
  • Excessive fatigue
Cognitive symptoms:
  • Memory loss
  • Confusion
  • Difficulty concentrating
  • Personality changes
  • Mood shifts
  • Depression or anxiety
  • Poor impulse control

Treatments also depend upon the condition & its causes but can include any combination of the following.

  • Medication.
  • Surgery.
  • Physical therapy.
  • Occupational therapy.
  • Lifestyle modifications.
