Cognitive Neuroscience

Image
  Cognitive Neuroscience Cognitive neuroscience is a subfield of neuroscience that studies the biological processes that underlie human cognition, especially in regards to the relation between brain structures, activity, and cognitive functions. The purpose is to determine how the brain functions and achieves performance. Cognitive neuroscience is considered as a branch of both psychology and neuroscience, because it combines the biological sciences with the behavioral sciences, such as psychiatry and psychology. Technologies that measure brain activity, like functional neuroimaging, can provide insight into behavioral observations when behavioral data is insufficient. Decision-making is an example of a biological process that influences cognition. What is Cognitive Neuroscience? The term itself refers to a subfield of neuroscience that studies the biological processes that underlie human cognition. This field studies the neural connections within the human brain. It helps in deter...

Mental Disorders

Image
A mental disorder is characterized by a clinically significant disturbance in an individual’s cognition, emotional regulation, or behaviour.  It is usually associated with distress or impairment in important areas of functioning. There are many different types of mental disorders.  Mental disorders may also be referred to as mental health conditions. The latter is a broader term covering mental disorders, psychosocial disabilities and (other) mental states associated with significant distress, impairment in functioning, or risk of self-harm.  This fact sheet focuses on mental disorders as described by the International Classification of Diseases 11th Revision (ICD-11). In 2019, 1 in every 8 people, or 970 million people around the world were living with a mental disorder, with anxiety and depressive disorders the most common (1). In 2020, the number of people living with anxiety and depressive disorders rose significantly because of the COVID-19 pandemic.  Initial es...

Stress, Anxiety and Depression

Image
Stress is a feeling of emotional or physical tension. It can come from any event or thought that makes you feel frustrated, angry, or nervous. Stress is your body's reaction to a challenge or demand. In short bursts, stress can be positive, such as when it helps you avoid danger or meet a deadline. Anxiety is a feeling of fear, dread, and uneasiness. It might cause you to sweat, feel restless and tense, and have a rapid heartbeat. It can be a normal reaction to stress. For example, you might feel anxious when faced with a difficult problem at work, before taking a test, or before making an important decision. Depression is a mood disorder that causes a persistent feeling of sadness and loss of interest. Also called major depressive disorder or clinical depression, it affects how you feel, think and behave and can lead to a variety of emotional and physical problems.

Alzheimer's disease

Image
  Alzheimer's disease is a progressive neurologic disorder that causes the brain to shrink (atrophy) and brain cells to die. Alzheimer's disease is the most common cause of dementia — a continuous decline in thinking, behavioral and social skills that affects a person's ability to function independently. Approximately 5.8 million people in the United States age 65 and older live with Alzheimer's disease. Of those, 80% are 75 years old and older. Out of the approximately 50 million people worldwide with dementia, between 60% and 70% are estimated to have Alzheimer's disease. The early signs of the disease include forgetting recent events or conversations. As the disease progresses, a person with Alzheimer's disease will develop severe memory impairment and lose the ability to carry out everyday tasks. Medications may temporarily improve or slow progression of symptoms. These treatments can sometimes help people with Alzheimer's disease maximize function and m...

Huntington's Disease

Image
Huntington's Disease:   Huntington's disease is a rare, inherited disease that causes the progressive breakdown (degeneration) of nerve cells in the brain. Huntington's disease has a wide impact on a person's functional abilities and usually results in movement, thinking (cognitive) and psychiatric disorders. Huntington's disease symptoms can develop at any time, but they often first appear when people are in their 30s or 40s. If the condition develops before age 20, it's called juvenile Huntington's disease. When Huntington's develops early, symptoms are somewhat different and the disease may progress faster. Medications are available to help manage the symptoms of Huntington's disease. But treatments can't prevent the physical, mental and behavioral decline associated with the condition. Symptoms: Huntington's disease usually causes movement, cognitive and psychiatric disorders with a wide spectrum of signs and symptoms. Which symptoms appe...

Central Nervous System Infections

Image
Central Nervous System Infections The central nervous system (CNS) is the part of the body’s nervous system that includes the brain and spinal cord. It controls most functions of the body and mind. An infection of the central nervous system can be a life-threatening condition, especially for children with weakened immune systems. These infections need quick diagnosis and immediate treatment by an infectious disease specialist. Bacteria, fungi and viruses are the most common causes of CNS infections. Central nervous system infections caused by bacteria or fungi can cause illnesses such as: Brain abscesses, Bacterial meningitis, Severe headache, Back pain, Stiff neck, Confusion, Weakness, Fever, Seizures, Paralysis, Viral meningitis , Encephalitis, Fever, Irritability, Not wanting to eat, High pitched cry, Head and neck pain, Seizures.

Neurological Infection

Image
Neurological infections encompass a large variety of conditions that invade and affect the nervous system. Despite advances in therapy and the development of early detection techniques, many of these conditions can cause severe, chronic and even life threatening problems for those affected by them. Several factors contribute to the widespread incidence of neurological infections, such as: The rising number of people infected with HIV/AIDS who are susceptible to neurological infection due to impaired immunity. The increasing use of immnosuppressant medications such as anti-cancer drugs that leave people vulnerable to neurological infection. Several viral infections of the central nervous system have emerged that are not yet amenable to available treatment. The geographical spread of neurological infections is increased through people’s frequent travelling and movement between region Symptoms Various different organisms can target the brain, spinal cord or peripheral nerves, with bacteri...
