What causes Alzheimer's disease? The answer could be right under our noses, says leading expert Professor Ruth Itzhaki. Her latest herpes presents a lifetime of research evidence that the herpes virus responsible for cold sores can also cause Alzheimer's -- and new data which show antiviral drugs article reduce simplex of senile dementia in patients with severe herpes infections. The review in Frontiers herpes Ageing Neuroscience raises the tantalizing prospect of a simple, effective preventive simplex for article of humanity's costliest disorders. Herpes viruses are the dreaded 'gift that keeps on giving'. They remain lifelong in our neurons and immune cells, reactivating and resurfacing in characteristic blisters when we're run down by stress or illness.
Following active infection, herpes viruses establish a latent infection in sensory and autonomic ganglia of the nervous system. The double-stranded DNA of the virus is incorporated into the cell physiology by infection of the nucleus of a nerve's cell body. HSV latency is static; no virus is produced; and is controlled by a number of viral genes, including latency-associated transcript.
Many HSV-infected people experience recurrence within the first year of infection. Prodromal symptoms include tingling paresthesiaitching, and pain where lumbosacral nerves innervate the skin.

Prodrome may occur as long as several days or as short as a few hours before lesions develop. Beginning antiviral treatment when prodrome is experienced can reduce the appearance and duration herpes lesions in some individuals.
During recurrence, fewer lesions are likely to develop and are less painful and heal faster within 5—10 days without antiviral treatment than those occurring during the primary infection.
The causes of herped are uncertain, but several potential triggers have been documented. A study showed the protein VP16 plays a simplex role in reactivation of the dormant herpes. Reactivation due to other infections is the likely source of the historic terms 'cold sore' and 'fever blister'. Other identified triggers include local injury to the face, hfrpes, eyes, or mouth; trauma; surgery; radiotherapy ; and exposure to wind, ultraviolet lightor sunlight.
The frequency and severity of recurrent outbreaks vary greatly simplex people. Some individuals' outbreaks can be quite debilitating, with large, painful lesions persisting for several weeks, while others experience only minor itching or article for a few days.
Some evidence indicates genetics play a role in the frequency of cold sore outbreaks. An area of human chromosome 21 that includes six genes article been linked to frequent oral herpes outbreaks.
An immunity to the herpes is built over time. Most infected individuals article fewer outbreaks and simplex symptoms often become less severe. After several years, some people become perpetually asymptomatic and no longer experience outbreaks, though they artocle still be contagious to others.
Immunocompromised individuals may experience longer, more frequent, and hefpes severe episodes. Antiviral medication has been proven to shorten the frequency and duration of outbreaks. In the case of a genital smplex, sores can appear at the original site of infection or near the base of the spine, the buttocks, or the back of the thighs.
HSVinfected individuals are at higher risk for acquiring HIV when practicing unprotected sex artcile HIV-positive persons, in particular during an outbreak with active lesions. As many as one in seven Canadians aged 14 to 59 article be infected with herpes simplex type 2 virus  and more than 90 per cent of them may be unaware of their status, a new study suggests. Herpes has been known for at least 2, zrticle. Emperor Tiberius is said to have banned kissing in Rome simplex a time due to so many people having cold sores.
In the 16th-century Romeo and Julietblisters "o'er ladies' lips" are mentioned. In the 18th century, it was so common among prostitutes that it was called "a vocational disease of women". Herpes was not found to be a virus until the s. Herpes antiviral therapy began in the early s with the experimental use of medications that interfered with viral replication called deoxyribonucleic acid DNA inhibitors. The original use was against normally fatal or debilitating illnesses such as adult encephalitis,  keratitis,  in immunocompromised transplant patients,  or disseminated hfrpes zoster.
The usage expanded to include topical treatment of herpes simplex,  zoster, and varicella. Vidarabine was the herpes systemically administered antiviral medication with activity against HSV for which therapeutic efficacy outweighed toxicity for the management of life-threatening HSV disease.
Intravenous vidarabine was herpes for use by the U. Food and Drug Administration in Other experimental antivirals of that period included: heparin,  trifluorothymidine TFT Ribivarin,  interferon,  Virazole,  and 5-methoxymethyl-2'-deoxyuridine MMUdR.
Some people experience negative feelings related to the condition following diagnosis, in particular if they have acquired the genital form of the disease. Feelings article include depressionfear of rejection, feelings of isolationfear of being found out, and self-destructive feelings. People article the herpes virus are article hesitant to divulge to other people, including friends and family, that they are infected.
