According to recent research, dementia patients worldwide, are predicted to increase to 74.7 million by 2030 and to 131.5 million by the year 2050.

Approximately 400,000 patients in Greece, have been diagnosed either with dementia or cognitive impairment. The percentage of elderly people with dementia in Greece is approximately 5%, while 75% of them have dementia due to Alzheimer’s disease. This number will double in the next 20 to 30 years.

Signs and Symptoms

Dementia and Alzheimer’s Disease

Disorders grouped under the general term “dementia” are caused by abnormal brain changes. These changes trigger a decline in cognitive abilities, severe enough to impair daily life and independent function. They also affect behavior, feelings and relationships.

In addition to the impairment of mental functions, dementia also has neuropsychiatric symptoms, which appear in almost all patients. The main symptoms concern disorders of perception, content of thought, emotion and behavior and can appear in all stages, even in the very early stages, of the disease.

The patient may have paranoid, delusional ideas, mainly visual hallucinations, depression, but also aggression, agitation, screams, sleep disorders and disinhibition.

Addressing Dementia and Slowing its Progression

Therapies with Laser Helmet with infrared light may help these patients, as intracranial Laser Therapy (Light Level Laser Therapy -LLLT) can enhance ATP biosynthesis, regulate mitochondrial homeostasis, and facilitate brain neurogenesis and/or neuroplasticity [1].

Clinical studies have found that LLLT could improve cognitive function and reduce depression, anxiety, headache, and insomnia in patients with chronic brain injury [2,3,4].

In addition, several studies have demonstrated the value of LLLT in increasing neurometabolic energy levels that can subsequently improve cerebral hemodynamics and cognitive abilities in humans [5].

Laser infrared light can slow the progression of neurodegenerative disease and reduce cortical β amyloid levels [6].
