Brain Atrophy & Hearing Loss:

 Brain Atrophy & Hearing Loss:

Dr. Frank Lin, an assistant professor at Johns Hopkins University in Baltimore, conducted a study that suggests a link between hearing loss, particularly in older individuals, and accelerated brain shrinkage. It has long been observed that older adults with hearing impairment experience faster declines in cognitive abilities and memory, but the underlying reasons remained a mystery until now.

This research discovered that older adults with hearing loss lose brain volume at a faster rate compared to their peers of the same age who have normal hearing. The exact reasons for this phenomenon and its implications for daily life remain unclear. However, it does raise an important question: Could treating hearing loss potentially slow down these brain changes and even mitigate the risk of dementia?

The study followed 126 adults between the ages of 56 and 86 over a 10-year period, subjecting each participant to annual MRI scans to track brain tissue loss. Nearly half of the participants had mild hearing loss at the beginning of the study.

The results indicated that individuals with hearing loss experienced a more rapid decline in brain volume compared to those with normal hearing. Notably, the areas of the brain responsible for processing speech and sound were the most affected.

Whilst the exact relationship between hearing loss and cognitive decline remains unclear, it is evident that hearing loss can impede social interaction and the brain's exposure to auditory stimuli. Therefore, even without concrete proof of causation, addressing hearing loss can enhance the quality of life, not only for the affected individual but also for those around them.

Knowledge management

Knowledge management (KM) is the process of capturing, developing, sharing, and effectively using organisational knowledge.[1] It refers to a multi-disciplined approach to achieving organisational objectives by making the best use of knowledge.[2] An established discipline since 1991 (see Nonaka 1991), KM includes courses taught in the fields of business administration, information systems, management, and library and information sciences (Alavi & Leidner 1999).[3][4] More recently, other fields have started contributing to KM research; these include information and media, computer science, public health, and public policy.[5] Columbia University, Kent State University and the University of Haifa offer dedicated Master of Science degrees in Knowledge Management.[6][7][8] Many large companies, public institutions and non-profit organisations have resources dedicated to internal KM efforts, often as a part of their business strategy, information technology, or human resource management departments.[9] Several consulting companies provide strategy and advice regarding KM to these organisations.[9] Knowledge management efforts typically focus on organisational objectives such as improved performance, competitive advantage, innovation, the sharing of lessons learned, integration and continuous improvement of the organisation.[10] KM efforts overlap with organisational learning and may be distinguished from that by a greater focus on the management of knowledge as a strategic asset and a focus on encouraging the sharing of knowledge.[2][11] It is an enabler of organisational learning. source: Wikipedia, the free encyclopedia

Latest Research Results on Cancer

Did you know the latest research results for the cause of cancer?

It says, it is not life style or genetic factors ,but it is biological bad luck.
Due to mutation of the cells.Read more here........

Most types of cancer can be put down to bad luck rather than risk factors such as smoking, a study has suggested.

A US team were trying to explain why some tissues were millions of times more vulnerable to cancer than others.

The results, in the journal Science, showed two thirds of the cancer types analysed were caused just by chance mutations rather than lifestyle.

However some of the most common and deadly cancers are still heavily influenced by lifestyle.

And Cancer Research UK said a healthy lifestyle would still heavily stack the odds in a person's favour.
