15^th Global Neurologists Meeting on Neurology and Neurosurgery November 08-09, 2023 Paris, France

The body's aberrant cell formation leads to the development of brain tumors. Tumors of the mind that start in the cerebrum are considered essential. Tumors of the brain have no recognized cause. Depending on their size, nature, and location, cerebral tumors can exhibit various symptoms. The most typical side effects of brain tumors include headaches, deadness or shivering in the arms or legs, seizures, memory problems, identity changes, adjust and walking problems, vomiting, regurgitating, and changes in speech, vision, or hearing.

Brain and spinal cord tumors are the subject of neuro-oncology research. Like astrocytoma, glioma, glioblastoma multiforme, ependymoma, pontine glioma, and brain stem tumors, many of these are exceedingly harmful and life-threatening.

In the world, there are more than 600 different neurological disorders. Two occurrences of intracranial subdural hematoma, nearly 248 cases of intracerebral malignant lymphoma, and 167 cases of extradural hematoma have all been documented.

The purpose of case studies on the neurology and neurosurgery track is to inform and inspire young researchers by sharing the real-world experience of scientists, researchers, and medical professionals with novel and serious neurological illnesses and traumas. It enables communication amongst researchers regarding novel techniques, medical studies, drug testing, and other facets of neurology and neurosurgery.

The brain and spinal cord make up the central nervous system (CNS), a part of the nervous system. The central nervous system's interneurons are made up of a diverse range of cells, including neuroglial cells. The main defenses of the central nervous system are the skull and spinal column, which serve as physical barriers to harm. A syrinx, an area with fluid beneath the bones in the CNS that functions as a shock absorber, is also present. The soft tissue in the brain and spinal cord grows after a CNS injury, putting strain on the limited space and, sadly, leading to major problems. It is very difficult to treat conditions of the central nervous system.

Neurosurgery is a subspecialty of neurology, which focuses on the diagnosis and care of diseases and injuries involving the brain, spinal cord, and nervous system. Many people are paid well for their expertise, yet these benefits are often accompanied by several daily challenges. Neurosurgeons have very complex and hard jobs; when they assess and diagnose their patients, their duties and tasks frequently change. Without these outstanding individuals, the field of neurology and medical treatments would not be as promising as they are today.

The focus of the medical specialty of epilepsy is on neurological system disorders. There are over 600 different types of epilepsy. Major kinds of epileptic disease are caused by genetic defects, spinal cord damage, or brain trauma. Muscle weakness, partial or complete paralysis, and other physical symptoms are all indications of epileptic disorders. the area of medicine that deals with the diagnosis and treatment of conditions affecting the nervous system's brain, spinal cord, and nerves. Neurologists are medical professionals that specialize in treating conditions affecting the brain, spinal cord, and other central nervous system organs. Epilepsy frequently lacks a clear etiology. However, a variety of factors, including as genetics, head trauma, brain abnormalities, infectious diseases, and prenatal traumas, can assist determine the circumstances.

Huntington's chorea is another name for Huntington's disease (HD), which is a genetic condition. Brain cells are killed as a result. Mood or cognitive impairments are the first symptoms. As the illness advances, uncoordinated, jerky bodily motions become more obvious. Physical capabilities decrease to the point that coordination is challenging and speech is lost. Dementia gradually develops as mental faculties generally decline. People may experience different specific symptoms. Although they can emerge at any age, symptoms often start to show between the ages of 30 and 50. Parkinson's symptoms are more comparable to those of Huntington's disease. Huntington's disease patients usually underrate how severe their symptoms are.

A syndrome known as dementia results in a loss of cognitive function (i.e., the ability to process ideas) that is more severe than what would be expected from the ordinary consequences of biological aging. Usually, it has a chronic or progressive nature. All of these functions—memory, direction, thinking, understanding, computation, learning capacity, language, and judgment—are affected. No one's state of consciousness is altered. Changes in mood, emotional control, behaviour, or motivation frequently coexist with and sometimes precede the deterioration of cognitive function

Dementia rates

More than 60% of the 55 million people with dementia worldwide live in low- and middle-income countries. Due to the fact that the proportion of older people in the population is rising in practically every nation, it is predicted that this number would rise to 78 million in 2030 and 139 million in 2050.

Neurodegeneration, also known as the progressive loss of structure or function of neurons, including the death of neurons, is the underlying cause of dementia. This condition affects both brain cells and neurons. There are several neurodegenerative illnesses that can lead to dementia, the most prevalent of which is Alzheimer's disease (AD), followed by Parkinson's-Lewy body disease (PD-LBD). Importantly, vascular brain illness (vascular cognitive impairment [VCI]) and neurodegenerative brain alterations are commonly linked, making mixed disease common in the elderly. It is believed that some conditions are incurable. However, nothing is now thought to be incurable or impossible by science. As the study goes on, it becomes clear that these diseases share a number of cellular commonalities, which raises the prospect of therapeutic advancements in the treatment of these conditions.

Up to one billion individuals worldwide are afflicted by neurological problems like epilepsy, Alzheimer's disease, stroke, and headache, according to a World Health Organization (WHO) report on neurology. According to estimates, neurological illnesses cause the deaths of 6.8 million individuals annually. There are more than 600 distinct disorders of the neurological system.

Neuro diagnostic tests involve the use of essential tools when a patient's condition is assumed to be based on the invention of methods that enable researchers to view inside the living brain and monitor nervous system activity. Because of this, there are many imaging methods accessible, and processing is time-consuming. To ascertain the presence of a certain condition or abnormality, some procedures are carried out in specialized facilities. numerous exams, including computed tomography (CT). Neuroimaging and magnetic resonance imaging (MRI), which were once done in a hospital, are now done at a doctor's office or at an outpatient testing facility with little to no risk to the patient.

A subfield of immunology and neurology is called neuroimmunology. Neuroscience and immunology are the two disciplines that investigate the neurological and immunological systems, respectively. Analysing the interconnections between these two intricate systems during development, homeostasis, and injury response is a goal of neuroimmunologists. The development of novel pharmaceutical therapies for a range of neurological disorders is aided by neuroimmunologists.

Neurotransmitters are endogenous substances that allow for neurotransmission. It is a sort of chemical messenger that sends signals across a neuromuscular junction from one target neuron to another. Neurotransmitters are released into the synaptic cleft by synaptic vesicles in synapses. Target cells' neurotransmitter receptors then detect them. Neurotransmitters play a crucial role in determining how our bodies work and behave. There have been almost 200 chemical messengers. in our body is uniquely identifiable.

A physician who specializes in neurology is called a neurologist. Neurologists do not do surgery; instead, they send patients who need it to neurosurgeons. They deal with conditions such those that impact the nerves, spinal cord, and brain such as:

• Cerebrovascular disease, such as stroke;
• Demyelinating diseases, such as multiple sclerosis;
• Headache disorder
• Spinal cord  disorders
• Speech and language disorders
• Infections of the brain and peripheral nervous system
• Movement disorders, such as Parkinson's disease
• Neurodegenerative disorders, such as Alzheimer's disease, Parkinson's disease
• Seizure disorders, such as epilepsy

The building blocks of the nervous system that conduct electrical impulses are neurons, also referred to as nerve cells. These are made to transmit information using an electrochemical technique. Dendrites, axons, Ranvier nodes, myelin sheath, and other structures make up this structure. Information is transmitted throughout the body with the help of neurons. Neurons can be of two different types. motor and sensory neurons.

The study of all illnesses affecting the central and peripheral nerve systems, as well as their coverings, blood vessels, and all effector tissue, including muscle, is the focus of the biological field of neurology. The scientific study of the growth, organization, and function of the nervous system is called neuroscience, and it is a field that has a significant impact on neurological practice. Additionally, it denotes when a person has psychological, neurological, or developmental issues. It also covers science, such as chemistry, philosophy, psychology, engineering, linguistics, and medicine.

A wide term used to describe impaired mental function brought on by a medical ailment other than a psychiatric illness is "neurocognitive disorder." The two different categories of cognitive diseases are major and mild neurocognitive disorders. Previously known as Major Neurocognitive Disorder, dementia is a condition. Neurocognitive diseases can impact any aspect of cognition, including memory, attention, learning, language, perception, and social cognition.

Conditions known as neuromuscular diseases damage the nerves that govern your voluntary muscles. These muscles are under the control of neuronal signals. When neurons die or become sick, communication between the nervous system and the muscles is disrupted. At this point, muscles deteriorate and become brittle. Twitching, cramping, aches, pains, joint problems, and problems with mobility are all signs of weak muscles. A list of neuromuscular conditions includes spinal muscular atrophy, multiple sclerosis, myasthenia gravis, and amyotrophic lateral sclerosis.

The two major medical specialties of neurology and ophthalmology unite to form the area of neuro-ophthalmology. The neurological manifestation in the visual system is what it actually implies. The optic nerve transmits visual information, hence harm to this organ could impair eyesight or perhaps cause permanent effects.

Pediatric neurology focuses on the identification and management of neurological conditions in new-born’s, infants, children, and adolescents. "Neuropediatric" refers to neurological conditions affecting children, such as anomalies of the brain, spinal cord, peripheral nervous system, autonomic nervous system, muscles, and blood vessels.

Treatment for mental diseases associated with neurological problems is provided by the medical specialty of neuropsychiatry. The sciences of neuropsychology and behavioural neurology are closely related to the growing topic of neuropsychiatry. Among the neuropsychiatric symptoms of Alzheimer's disease include psychosis (delusions and hallucinations) and behavioural abnormalities such gloomy mood, anxiety, anger, apathy, euphoria, disinhibition, aggression, aberrant motor movements, sleep trouble, and food disorder.

The study of the structure, operation, and particular psychological processes and behaviors of the brain is known as neuropsychology.  It tries to comprehend how brain functioning influences behaviour and cognition and focuses on the diagnosis and treatment of the behavioural and cognitive effects of neurological diseases. As a result, neuropsychology usually studies the relationship between the brain and the mind. As a result, it shares concepts and problems with neuropsychiatry.

Neuropharmacology is the study of how drugs alter the neural circuits that control behaviour as well as the cellular processes that occur in the nervous system. Its two prominent subfields are behavioural and molecular neuropharmacology. The primary goal of behavioural neuropharmacology is to understand how drugs impact behaviour, particularly the mind's response to drug abuse and dependency.

The scientific study of the nervous system is referred to as "neuroscience." It focuses on the examination of brain system development. Neurons help to transmit information throughout the body. As a result of the rising number of publications in the field of neuroscience

The goal of the medical specialty of neurosurgery is to diagnose, surgically treat, and provide rehabilitation for conditions affecting any component of the nervous system, including the brain, spinal cord, peripheral nerves, and extracranial cerebrovascular system. Both adult and child patients are covered under the neurosurgical speciality. A neurological surgeon may recommend surgery or non-surgical treatment options depending on the type of injury.

Neurotherapeutics is a quarterly peer-reviewed medical journal that covers research on innovative treatments for neurological diseases. In the field of neurology, the process of making diagnoses and discovering new drugs has dramatically risen.

Neuro-therapeutics is a start-up in the field of digital health that is committed to developing hardware and software platforms that greatly improve brain health.

As a movement disorder, Parkinson's disease is the second most prevalent neurodegenerative condition. Some individuals only experience a slight tremor in one hand at first, and it gets worse with time. Although a tremor is perhaps the hallmark of Parkinson's disease, it is also usually accompanied by solidity or a halting of growth. In the early stages of Parkinson's disease, the patient may show almost little facial expression or walk without swinging their arms. They could appear to have sensitive or slurred speech. As the patient's condition deteriorates over time, the symptoms of Parkinson's disease get worse. There have been considerable improvements in our understanding of Parkinson's disease in recent years.

The initial stage of mild memory loss, which is most likely caused by an inability to do important tasks, is Alzheimer's disease. Alzheimer's disease is a mental condition that slowly robs people of their memory, their capacity to reason, and even their ability to perform the most fundamental tasks. Dementia that is caused by Alzheimer's disease deteriorates over many years. Although Alzheimer's disease begins with little memory loss, as the illness advances, it gets harder to carry out daily tasks and interact with other people. Alzheimer's has no known cure, but there are effective treatments for the symptoms, and research is ongoing.

When there is a decrease or restriction in the cerebral blood flow, a stroke happens. Conditions like ischemia and haemorrhage can arise on their own. This could be hastened by blood clotting-causing bottlenecks in the blood supply pathways to the brain. The coagulation is caused by the oily reserves in the conductors. Additionally, extra supply lines in the brain may rupture or spill blood, leading to a stroke. Having difficulties seeing out of one or both eyes; having a dead face, arm, or leg, especially on one side of the body; and having trouble walking, including confusion and lack of coherence. The already mentioned indicates a minimal quantity of stroke.

Multiple sclerosis (MS) (central nervous system) is a potentially debilitating brain and spinal cord disorder. Multiple sclerosis (MS) causes the immune system to attack myelin, the protective sheath that shields nerve fibers, which obstructs the communication between your brain and the rest of your body. In the end, the illness may cause irreversible damage to the nerves or nerve degeneration.
