Baltimore, Maryland, or senile dementia caused by damage and decline in cognitive function in the brain. Because the brain is the central coordination of the whole body, brain cell damage in people senile also affect various organ systems including the sense of hearing.

Decreased ability to hear at 10 decibels (dB) indicates an increased risk of dementia by 20 percent. The greater decline in auditory function that happens, the sooner a person will experience a decline in cognitive function alias senile.

This is evidenced by Dr. Frank Lin, a researcher from Johns Hopkins Medical Institution in Baltimore in recent research. Research conducted during the 18 years that involved 639 participants aged 36-90 years, who do not have signs of dementia at the start of the study.

During the observation, mild hearing impairment (25-40 dB) occurred in 125 participants, moderate (41-70 dB) for 53 participants and severe (more than 70 dB) at 6 participants. When compared, the magnitude of hearing impairment was directly proportional to the decline in cognitive function.

“Deaf can be early signs of dementia. If the anticipated since now, the number of people with dementia can be reduced 10 percent by 2050,” Dr. Lin said in a report in the journal Archives of Neurology, as quoted by the Telegraph, Tuesday (15/02/2011) .

Previously, various studies have also been conducted to reveal early signs of senility. Experiments on mice at New York University revealed that the early symptoms of dementia characterized by the reduced sense of smell, while the Mayo Clinic researchers linked an increased risk of dementia with sleep disturbance.

In addition, researchers from the University Hospital of Madrid have revealed that the majority of sleep can increase the risk of dementia. Other conditions that cause people faster senile aka belly bulge is central obesity as revealed by the researchers from the University Victor Segalen Bordeaux.

“If someone had a strange personality, is not sensitive when brutalized and gullible then he should immediately contact a specialist,” said the researcher, Katherine Rankin as quoted from Time

Frontotemporal dementia is a type of dementia is rare, striking just 5 percent of all cases of dementia in general. Compared to Alzheimer’s, frontotemporal dementia types attacking the younger age group is between 40-70 years.
