Dementia is not a single disease in itself; it is symptoms of loss of memory, communication, and thinking. Dementia increases with age. In every 4seconds there is a new case of dementia. Old people are mostly affected by dementia. Alzheimer’s disease is one of the types of dementia. This is caused because of protein abnormalities. Brain tissue of the person suffering from Alzheimer’s disease has less number of cells and the brain shrinks. Alzheimer’s disease is caused by lifestyle, genetics, and factors that affect the brain. Parkinson’s disease damages nerve cells in the brain which produces dopamine and the decrease in the dopamine levels causes abnormal activity that result in Parkinson’s disease. This disease is caused mainly due to loss of neurons which produces dopamine.

Epilepsy could be a chronic disorder that causes wanton, repeated seizures. A seizure could be an abrupt rush of electrical activity within the brain. There are 2 main forms of seizures. Generalized seizures have an effect on the entire brain. Focal or partial seizures have an effect on only 1 a part of the brain. A light seizure could also be tough to acknowledge. It will last many seconds throughout that you lack awareness. Brain disorder could be a fairly common neurological disease that affects sixty five million folks round the world. It affects concerning three million folks. Anyone will develop brain disorder; however it’s a lot of common in young kids and older adults. It happens slightly a lot of in males than in females.
Neuroimaging or brain imaging is that the employment of various techniques to either directly or indirectly image the structure, function, or medical specialty of the system. It is a relatively new discipline within medicine, biology, and science. Physicians administrative unit focus on the performance and interpretation of neuroimaging at intervals the clinical setting unit neuroradiologists.

As a branch of medication, gerontology thinks about with diagnosis and treating diseases that occur in adults, usually over age sixty. A set of this, geriatric neurology focuses on medicine disorders common to the current people. Older patients usually gift with overlapping issues from numerous disorders, the results of natural ageing are often tough to disentangle from clinical conditions, and blurry syndromes square measure common.
Multiple sclerosis (MS) is a chronic illness involving your central nervous system (CNS). It can affect your brain, spinal cord, and the optic nerves in your eyes. It happens once your system attacks a fatty material referred to as fat, which wraps around your nerve fibers to shield them. Without this outer shell, your nerves become damaged.
Symptoms:
Fatigue
Thinking Problems
Vision Problems
Optic Neuritis
Depression
Pain

Neuropathology is the study of pathology focused on the disease of brain, spinal cord and neural tissue. This consists of both central nervous system and the peripheral nervous system. Neuropathologist’s works in the department of anatomic pathology for diagnosis. Tissue analysis appears from either surgical biopsies or post mortem autopsies and this tissue samples include muscle fibers and nervous tissue. Brain disease or brain injury can be related to brain death.
Neurogenomics is the study of an organism influences the development and function of its nervous system. Neurogenomics investigates connections among genotypes, phenotypes, and the earth, utilizing a scope of genomic and bioinformatics ways to deal with integrate datasets catching various levels of sensory system function This field intends to unite functional genomics and neurobiology in order to understand the nervous system in the from a genomic perspective.
Clinical neurophysiology is a therapeutic specialty that studies the central and peripheral nervous systems through the documentation of bioelectrical activity, whether spontaneous or stimulated. It involves the study of both pathophysiology along with clinical methods used to diagnosis both in peripheral and central nervous system. Examinations in clinical neurophysiology field are not limited to tests conducted in a laboratory. Tests which are conducted are concerned with measuring the electrical functions of the brain, nerves in the limbs & muscles and spinal cord.

Paediatric neurology happens mostly in youngsters or teenagers. Neurology influences around 6 in 100,000 youngsters. Neurology in kids is of three essential sorts in whom two are ischemic neurology in which blockage of veins outcome in absence of blood stream and harm. At the point when a corridor is blocked, the term blood vessel ischemic neurology (AIS) is utilized. At the point when a vein is block, the term utilized is cerebral Sino venous thrombosis (CSVT). In the third shape, haemorrhagic neurology (HS), the vein crack as opposed to being blocked. The most known signs and side effects of neurology incorporate the sudden appearance of failing or deadness of the face, arm or leg, more often than not on one side of the body.

Neuromuscular disorders affect the nerves that control your own voluntary muscles. Voluntary muscles are the ones which we can control by our self like in your arms and legs. Your nerve cells also called as neurons, send the messages that control these muscles. When the neurons become delicate or die, communication between your nervous system and muscles breaks down. As a result, your muscles weaken and waste away this weakness can lead to twitching, cramps, aches, pains, and joint and movement problems. Frequently it also affects heart function and your ability to breathe.

Spine disorders occur in individuals irrespective of their age -spina bifida in infants to spinal stenosis in the elderly. Causes of spinal cord disorders include mainly injuries, infections, blocked blood supply, and compression by a fractured bone or a tumor. The boost in spinal disorders has been met with a leap in advancements in the diagnostic techniques. Endoscopic spine, MRI, X- rays CT and DEA are some of the generally used tools in diagnosing spinal disorders.

Neurogenetic and neurometabolic abnormalities are disorders that affect how the brain functions. They occur in young children of all ages, races and genders. Neurogenetic disease is the umbrella term of chronic diseases which describe the brain abnormalities that occur following changes in the genes of the child and these cause certain brain cells to develop and function abnormally. In the case of neurometabolic abnormalities; these disorders result from problems in the enzymes of the body’s cells which are either unable to either use foods to produce the energy the cell needs, or get rid of the breakdown products of the foods used.

Neurodegeneration is the progressive loss of both structure or functioning of neurons, including their death. Many neurodegenerative diseases- including amyotrophic lateral sclerosis, Parkinson's disease, Alzheimer's disease, fatal familial insomnia, and Huntington's disease- occur as a result of neurodegenerative processes. Such diseases are incurable and cause problems with movement (ataxias), or mental functioning (dementias). Of these Alzheimer’s disease and Parkinson’s disease are the most common ones. It is observed that the combination of a person’s genes and the related environment contributes to the risk of developing a neurodegenerative disease

Despite major advancements in the management of infectious diseases, central nervous system (CNS) infections remain a great challenge. They are often difficult to diagnose, and treatments are not adequate or even nonexistent. Bioterrorism is a threat because CNS pathogens can be used as weapons. Human and animal products for treatment also involve risk. There is a need for monitoring of incidence and burden of undiagnosed CNS infections. Lack of Treatments to Neuroinfectious Diseases is also a major challenge. Neuroimmunological disorders consist of diseases in which the immune system attacks the central or peripheral nervous systems. Deregulation of both adaptive and acquired immune responses, impairment of crosstalk between these two systems, as well as alterations in sequence of innate immune mechanisms can predispose the central nervous system (CNS) to autoimmunity and neurodegeneration. Multiple sclerosis is a type of neuroimmunological disorder that affects many people that features CNS inflammation, immune-mediated demyelination and neurodegeneration.

The brain is the most complicated organ in our body. Every area has a specific function that controls everything that we do. For years, doctors have had a rough map of the brain, but never to the degree that they could operate and know for sure how to avoid every critical portion since each person’s brain are unique, causing variations in the map. This fact, combined with the sheer complexity of the brain, has challenged neurosurgeons for years.
A biomarker is a characteristic that is objectively measured and evaluated as an indicator of normal biological processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention. Biomarkers for neurological diseases used to be few and far between, but better technology is making it easier for researchers to track brain health by measuring molecules. This means less invasive.
A stroke is a “brain attack”. It occurs when blood flow to an area of brain is cut off. When this happens, brain cells are deprived of oxygen and begin to die. When brain cells die during a stroke, abilities controlled by that area of the brain such as memory and muscle control are lost. Stroke is a disease that affects the arteries leading to and within the brain. It is the No. 5 cause of death and a leading cause of disability in the United States. A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts (or ruptures). When that happens, part of the brain cannot get the blood (and oxygen) it needs, so it and brain cells die.

Gliomas are brain tumours starting in the glial cells. Gliomas can be low grade (slow growing) or high grade (fast growing). The position of the tumour is also very important. Glioma is a type of tumor that occurs in the brain and spinal cord. Gliomas begin in the gluey supportive cells (glial cells) that surround nerve cells and help them function. The symptoms, prognosis, and treatment of a glioma depend on the person’s age, the exact type of tumor, and the location of the tumor within the brain.

Neurosurgery is an important part of medicine, working to protect, heal and treat the brain. There are many reasons an individual may need a neurosurgeon, ranging from an issue present at birth to treating a spinal cord injury caused by trauma or even to decrease the damage caused by a stroke. The Clinical Neurological nursing program provides patient-centred care to acute neurology and neurosurgical patients. Specialty care in neurology includes Epilepsy, Movement Disorders, Neuromuscular Disorders, Regional Stroke Program, Regional Multiple Sclerosis Clinic, and Neuro-Critical Care. Neurosurgery Care includes Neurovascular, Neuro-oncology, Spinal Surgery, Spinal Cord Injury, Head Injury, and Epilepsy Surgery.

Cognitive neuroscience is the scientific field that is concerned with the study of the biological processes and aspects that underlie cognition, with a specific focus on the neural connections in the brain which are involved in mental processes. It addresses the questions of how cognitive activities are affected or controlled by neural circuits in the brain. Cognitive neuroscience is a branch of both neuroscience and psychology, overlapping with disciplines such as physiological psychology, cognitive psychology, and neuropsychology. Cognitive neuroscience relies upon theories in cognitive science coupled with evidence from Neuropsychology, and Computational modelling.

Brain health refers to how well a person’s brain functions across several areas. Brain health can be affected by age-related changes in the brain, injuries such as stroke or traumatic brain injury, mood disorders such as depression, substance use disorder or addiction, and diseases such as Alzheimer’s disease. While some factors affecting brain health cannot be changed, there are many lifestyle changes that might make a difference.
Aspects of brain health include:
Cognitive health — how well you think, learn, and remember
Motor function — how well you make and control movements, including balance
Emotional function — how well you interpret and respond to emotions (both pleasant and unpleasant)
Tactile function — how well you feel and respond to sensations of touch — including pressure, pain, and temperature
