Ageing is a normal process that often involves a decline in human function - among them, cognitive ability. As you age, you may notice changes in your memory, mental speed, and problem-solving ability, significantly impacting an individual's overall quality of life in both physical and mental health, often finding it disheartening to see tasks once simple turn into something strenuous or high-effort. Recent advancements in LED light treatment, notably photobiomodulation (PBM), provide a viable approach for mitigating these effects. The team at Rojo Light Therapy NZ discusses how PBM can improve brain function in older individuals, emphasising key data from a major study published in PubMed.
Photobiomodulation, often known as red light treatment, involves the use of specific wavelengths of light to instigate or prompt certain biological processes in the body - through which, we’re able to enjoy the benefits of its physiological responses. In neurology, PBM often employs red or near-infrared light to penetrate the skull and target brain cells. The light absorbed by the cells causes a series of biological events, including increased ATP production, enhanced blood flow, and reduced inflammation. Collectively, these effects improve brain health and cognitive performance.
The study in question, published in the PubMed database, looks into the effects of PBM on brain function in 30 older adults. The researchers conducted a placebo-controlled study on older adults with mild cognitive impairment (MCI). The participants went through a series of PBM sessions using near-infrared light - here were some of their findings:Â
Improved Memory and Learning: The study discovered significant improvements in the participants' ability to retain information. Those who received PBM treatment performed better on memory recall tests than the placebo group, and showcases how PBM promotes neuroplasticity, the brain's ability to form new neural connections.
Enhanced Mood and Reduced Anxiety: The results demonstrated an improvement on mood and anxiety levels. The PBM-treated group reported reduced depression and anxiety symptoms, both of which are typical in older adults experiencing cognitive loss.
Higher Cerebral Blood Flow: The researchers discovered that the PBM-treated group had enhanced cerebral blood flow. Improved blood flow ensures brain cells receive enough oxygen and nutrients, enabling optimal performance and repair.
Neuroprotective Effects: PBM has neuroprotective qualities that reduce oxidative damage and inflammation. These factors are contributors to neurodegenerative disorders such as Alzheimer's. With these features, LED light treatment has the potential to slow down or prevent additional cognitive impairment.
The positive effects of PBM can be linked to a variety of underlying mechanisms:
Given the favourable results of clinical trials - much like the one reported here - LED light therapy is continuing to emerge as a viable, non-invasive approach to enhancing brain function in older adults. Rojo Light Therapy NZ provides cutting-edge PBM equipment designed to produce wavelengths that promote cognitive well-being.
One of the key benefits of LED light treatment lies in its safety and ease of use. Unlike pharmaceutical treatments, PBM is non-invasive and has few side effects. Rojo Light Therapy NZ offers portable gadgets that let you receive therapy in the comfort of your own home.
