ENCEPHALITIS
Encephalitis literally means an inflammation of the brain, but it usually refers to brain inflammation caused by a virus. It may also be called “acute viral encephalitis or aseptic encephalitis';. Encephalitis is an infectious disease of the Central Nervous System characterized by pathologic changes in both the gray and white matter of the spinal cord and brain. It may be due to specific disease entity such as rabies or an arthropod-borne virus (arbovirus), or it may occur as a sequela of influenza, measles, German measles, chicken pox, herpes virus infection, small pox, vaccinia, or other diseases. The specific viruses involved may vary. Exposure can also occur through insect bites, food or drink, or skin

Encephalitis is a neurological disorder that results in the inflammation of the brain and sometimes the meninges. It is usually due to a viral infection. Most often arboviruses cause encephalitis, by transference via mosquitos to humans and animals. When bitten by an infected mosquito the virus moves from the mosquito into the person’s blood, it then reaches the brain and spinal cord, it multiplies within the central nervous system thus inflaming and damaging nerve cells, this interferes with signals from the brain to the rest of the body. The herpes simplex virus type one can commonly cause encephalitis. HIV has also been noted as an increasing cause of encephalitis. Viral infections like: mumps, chicken pox and measles can also cause encephalitis, but rarely.
Liaw and Shen (1991) observed four children aged four to nine-years-old with AIWS associated with EBV infection. Episodes of perceptual distortions in body schema and objects lasted between five days to three months following infection of acute EBV. With the use of EEG and CT scans, the symptoms of AIWS appeared to be caused by benign and transient EBV infections localized in the parietal lobe. In addition to this, the perceptual distortions were also associated with infection of the temporal and occipital lobe in this sample of children. Since EBV compromises the central nervous system, the researchers suggest that incidences of AIWS are often the first and predominant symptom of EBV infection. An acute EBV infection can result in infectious mononucleosis (Saldana et. al, 2012), so it is important to also consider the long-term consequences of prolonged EBV
belonging to the genus Alphavirus and family Togaviridae. The majority of infected individuals experience sudden onset of fever, chills, headache, and decreased consciousness for several days1. EEEV infection progresses rapidly to neurological disease with symptoms such as seizures, paralysis or coma becoming visible 4-10 days after infection. Approximately 30-80% of people infected with EEEV die, and the majority of those who recover are left with mild to extensive long-term neurological damage1. There are currently no licensed vaccines or treatments available for EEEV. Existing vaccines are limited to US military forces and laboratory researchers
People suffer from many different mental diseases that lead to death. One of these diseases is CTE. This disease is found most commonly in athletes, military veterans, and others with the history of repetitive brain trauma. These athletes are mostly football players who suffer from repetitive brain injury from head on collisions. CTE stands for Chronic Traumatic Encephalopathy which is a progressive degenerative disease of the brain found in people with a history of repetitive brain trauma. Chronic Traumatic Encephalopathy or CTE is a very consequential condition that should be taken seriously to help prevent health disorders in the future.
Edgar Allen Poe died at only 40 years old but of what? Poe suffered from hallucinations, confusion, and hydrophobia. All three are signs of rabies. I believe that Poe died from rabies because, there is more evidence of rabies than there is of alcoholism.
Infrequent findings attributed to monkeypox were necrotizing conjunctivitis and thyroiditis. We detected antigen within conjunctival epithelial cells and fibroblasts. Because of the limited extent of the thyroid lesion, insufficient material was available for IHC.
Clinical syndromes are never pathognomonic for a paraneoplastic aetiology and a high index of clinical suspicion is important. Symptoms can be atypical, psychiatric or even fluctuating and PNS should often be in the differential diagnosis of otherwise unexplained severe neurological syndromes. Radiologic findings are especially important to rule out other possible causes; in case of PNS they often render aspecific findings. As an exception, CT and MRI reveal temporal lobe abnormalities in 65-80% of patients with limbic encephalitis (LE)(Dalmau and Rosenfeld 2008) and often some degree of cerebellar atrophy is seen in the chronic stage of predominantly cerebellar syndromes. In patients suffering from paraneoplastic cerebellar degeneration (PCD),
According to the CDC (2015), the Japanese encephalitis virus is a flavivirus just like the yellow fever and West Nile virus. Flaviviruses are mostly transmitted through bug bites, such as an infected mosquito.
What is West Nile Fever? West Nile fever also known as West Nile virus is a mosquito borne disease transferred from mosquito to person. Encephalitis is a disease that West nile virus can cause. What encephalitis does is it causes inflammation of the brain which in some cases can be fatal. The west Nile virus wasn’t discovered until 1937 in Africa. The disease didn’t make its way into the United States until 1999. The Virus is most common during the summer months (July- September) which is when mosquitos the carrier of the disease are most active. But in some states it is at risk all year round. Most people who are bitten and infected even receive the virus.

Dementia is one example of a neurological disorder. Jeffrey L. Cummings, and Michael R. Trimble (1995), explain that, “Dementia is a clinical syndrome characterized by an acquired persistent impairment in at least three of the following domains of function: language, memory, visuospatial skills, executive abilities, and emotion” (p.136). Patricia Lacks states in, Screening for Brain Dysfunction (1999), that Bondi, Salmon, and Kaszniak (1996, p.167) revealed that, “Recent research on dementia caused by Alzheimer’s disease suggests that the ‘hippocampus and entorhinal cortex are involved in the earliest stage of the disease and that frontal, temporal, and parietal association cortices become increasingly involved as the disease progresses”
Caprine Arthritis Encephalitis affects goats but there are cases that it can also affect sheep but it is less common. In goats, the disease is more prevalent in dairy goat breeds than in meat- and fiber-producing goats. This variation does not lie on genetics alone but by management practices like the feeding of colostrum from a single dam to multiple kids and other industrialized farming practices. As age is increased, so is the risk for the disease. Those that are affected at an early age remains affected for life and manifest the clinical signs months to years later. (Lofstedt, 2014). The CAE virus is intimately associated with white blood cells; therefore body secretions that contain blood cells are potential sources of virus to other
Encephalitis is a condition caused by viruses which cause the brain to become inflamed. There are two types of encephalitis one is called primary because the viruses affect the brain itself. Secondary is the viruses travel from some other part of the body that has been affect to the brain. When the virus reaches the brain it begins to multiply causing inflammation. The brain’s white matter can be destroyed. This destruction causes cell death, hemorrhage and edema. The edema begins to compress the blood vessels this causes intracranial pressure (Mayo Clinic, 2011).
Meningitis is an inflammation of the meninges, membranes that surround the brain. This can extend as far as infecting the cerebral spinal fluid on top of causing the tissue to swell. Meningitis comes in two major forms; bacterially and virally. However, having bacterial meningitis is much more severe than viral meningitis. There is a lot more danger in having a bacterial infection within the brain than a viral infection within the brain. What makes bacterial meningitis so lethal is that “even when the disease is diagnosed early and adequate treatment is started, 5% to 10% of patients die, typically within 24 to 48 hours after the onset of symptoms. Left untreated, up to 50% of cases may die, (6) or there
