Basic information of the Neurologist 
Neurology is the branch of medical science that deals with diagnosing and treating the diseases of the nervous system. It is a very complex system and has two primary divisions: 

  1. Central nervous system
  2. Peripheral nervous system

The central nervous system (CNS) consists of the brain and the spinal cord and the peripheral nervous system (PNS) consists of nerve fibres that carry information between the CNS and other parts of the body (the periphery). A neurologist doctor is the one who treats nervous system problems. In this growing world of technology and digital world you can opt for neurologist online consultation to understand what treatment is required for your problem. 
PNS is further subdivided into the afferent and the efferent divisions. The afferent division carries information to the CNS keeping it informed of the changes in the external environment. In the same way, the efferent division communicates from the CNS to the organs that are responsible for the ultimate functioning to get the desired effect. These organs include the muscles or glands that are responsible for normal function. Again the efferent part has two subdivisions, the somatic and the autonomic nervous system (ANS). Nerve fibers of the motor neurons supplying the skeletal muscles form the somatic nervous system and the ANS contains the nerve fibers that innervate smooth muscle, cardiac muscle and glands. The further subdivisions of the ANS are the sympathetic and the parasympathetic nervous system. These two innervate almost all the organs that is supplied by the ANS.

Functions of the CNS:
CNS consists of the brain and the spinal cord. The cells of the CNS that are involved in the function of communication are called neurons. There are an estimated 100 billion neurons. These do not work in isolation but are assembled into complex networks that enable one to

  • Subconsciously regulate internal environment by neural means
  • Experience emotions
  • Control movements voluntarily
  • Perceive one’s own body and the surroundings, and
  • perform higher cognitive processes, such as thought and memory


Cognition is defined as the process of knowing which encompasses both awareness and judgement. The different parts of the brain work in conjunction by the means of networks of synapses and the neurons present throughout the brain use electrical and chemical means to communicate with each other. However, neurons that work together to achieve the desired result are organized within a discrete location and thus the brain is organized into different regions while functioning as a whole. The brain can be divided into following parts:

  • Brain stem
  • Cerebellum
  • Forebrain
  • Hypothalamus
  • Thalamus
  • Basal ganglia
  • Cerebral cortex

The most complex of the all is the cerebral cortex. The cells of the nervous system that protect the neurons are called glial cells or neuroglia and they constitute about 90% of the total cells of the nervous system. 

Since the nervous system is central to the functioning of the whole body, any injury, lesion, infection or trauma to any of the organs or associated structures can have profound implications consequently having a very poor quality of life. There is high prevalence of neurologic diseases and the average cost of treatment is high. According to estimates by the World Health Organization (WHO), over 1 billion people worldwide are affected by neurologic disorders, 12% of the global burden of disease is neurologic diseases and these cause 14% of global deaths. With the advances in medical science, a number of therapies are available for many neurologic disorders, a skillful approach to diagnosis is essential. Adequate history and examination should precede neuroimaging procedures and laboratory tests. The clinical problem should be properly evaluated by knowing the anatomic location of the problem and the pathophysiology of the disease involved. 

The common diseases that occur are:

Seizures (Epilepsy):
It is caused by abnormal and excessive synchronous cortical firing of the neurons in the brain. Depending on the location and distribution of the neurons involved, there can be various manifestations ranging from excessive convulsive activity to hardly observable experiential phenomena. Epilepsy is defined as a condition where there are recurrent episodes of seizures. It is basically a phenomenon rather than a disease. There are various epilepsy syndromes with differing symptoms and different causes. The main diagnostic procedure is the EEG (electroencephalogram) but it should be done while the patient is experiencing seizure. There are different type of seizures. These are:

  • Focal onset seizures
  • Generalized onset seizures
Focal onset seizures are, as the name suggests, localized to a particular part of the brain and generalized onset seizures occupy much larger part of the brain. 

Stroke:
It is defined as the abrupt onset of a neurological deficit which is caused by a localized vascular problem. Depending on the area of the brain involved, the signs and symptoms occur. It is one of the leading causes of deaths and physical disability worldwide. 

Migraine:
It is the second most common cause of headache and causes severe pain along with other symptoms like sensitivity to light and sound, nausea and vomiting and sometimes the presence of aura (flashes of light or zigzag lines appearing in the visual field). Vertigo and dizziness are also associated in one third of the patients. 

Alzheimer’s disease:
It is a memory impairment disease that is practically untreatable and very common in India. More than 10 lakh cases are diagnosed each year and usually occur in persons aged more than 70 years. It usually starts with problems in memory and then progresses to language and visuospatial deficits. In the early disease, there are other symptoms that are not related to memory problems. These include difficulties with language, movement execution or perception. Older memories like episodic memory, semantic memory (learned facts) and implicit memory (the memory of the body on how to do things, such as using fork to eat or how to drink from glass) are affected to a lesser extent than new memories or facts. As the disease progresses, so many problems related to day to day activities start. These include problems in walking, eating, recognizing close relatives, etc. The patient also starts to have delusions and illusionary misidentifications. The death is eventually caused by some external factor like some infection.

Parkinsonism:
This is one of the major disorders that affects the elderly and is a cause of physical disability. The major symptoms include tremor at rest, slowness of movement, postural instability and rigidity. The causes can be drug induced or due to age related problems. 

Dementia:
It is defined as amnesia that usually develops in advanced age. The patient might forget some of the events. In the beginning, it might not cause much problems but eventually it starts interfering with the normal activities of the patient and can become quite worrisome affecting the quality of life of the patient. 

Movement disorders:
This usually occur due to lesions or other problems in the cerebellum. The patient is not able to keep his/her posture steady and constantly shakes. This is body’s mechanism to keep balance and equilibrium. 

Multiple sclerosis (MS):
It is a demyelinating disease in which the myelin sheath of the nerve cells of the brain and the spinal cord is destroyed thus affecting the transmission of signals. It is the most common autoimmune disorder affecting the central nervous system. The symptoms usually include double vision, blindness in one eye, muscle weakness and trouble with sensation and coordination. The symptoms may occur as isolated attacks or build up over time. Sometimes the symptoms totally disappear between attacks. The cause is unknown but it is thought that the immune system attacks the myelin sheath or the myelin producing cells are unable to produce myelin. There is no cure of MS as of now but conservative treatments can help improve the quality of life of the patient. 

The other less common disorders include:
  • Trigeminal neuralgia
  • Bell’s palsy
  • Glossopharyngeal neuralgia
  • Spinal cord disorders
  • Neuromyelitis optica
  • Myasthenia gravis
The medical science that deals with diagnosing and treating the diseases of the nervous systems is called a neurology and the doctor who specializes in this field is called a neurologist. Neurologists help in diagnosing the diseases by conducting various tests and procedures and if surgical intervention is needed, they refer the patient to a neurosurgeon who specializes in the surgery of the brain. In this growing world of technology and digital world you can opt for neurologist online consultation to understand what treatment is required for your problem.
