  2. Radiation-induced cognitive decline - Wikipedia

    en.wikipedia.org/wiki/Radiation-induced...

    For people with brain tumors, radiation can be an effective treatment because chemotherapy is often less effective due to the blood–brain barrier. [ citation needed ] Unfortunately for some patients, as time passes, people who received radiation therapy may begin experiencing deficits in their learning, memory, and spatial information ...

  3. Electromagnetic radiation and health - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_radiation...

    Exposing skin to infrared radiation near visible light (IR-A) leads to increased production of free radicals. [41] Short-term exposure can be beneficial (activating protective responses), while prolonged exposure can lead to photoaging. [42] Another important factor is the distance between the worker and the source of radiation.

  4. Functional near-infrared spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Functional_near-infrared...

    Functional near-infrared spectroscopy (fNIRS) is an optical brain monitoring technique which uses near-infrared spectroscopy for the purpose of functional neuroimaging. [1] Using fNIRS, brain activity is measured by using near-infrared light to estimate cortical hemodynamic activity which occur in response to neural activity.

  5. Binswanger's disease - Wikipedia

    These symptoms usually coincide with multiple falls, epilepsy, fainting, and uncontrollable bladder. [5] Because Binswanger's disease affects flow processing speed and causes impaired concentration, the ability to do everyday tasks such as managing finances, preparing a meal and driving may become very difficult. [3]

  6. Frontotemporal dementia - Wikipedia

    en.wikipedia.org/wiki/Frontotemporal_dementia

    Signs and symptoms are classified into three groups based on the affected functions of the frontal and temporal lobes: [8] These are behavioural variant frontotemporal dementia, semantic dementia, and progressive nonfluent aphasia. An overlap between symptoms can occur as the disease progresses and spreads through the brain regions. [14]

    Later, when the subjects were shown new images in the fMRI, the system detected the patient’s brain waves, generated a shorthand description of what it thinks those brain waves corresponded to ...

  8. Alzheimer's disease - Wikipedia

    en.wikipedia.org/wiki/Alzheimer's_disease

    The first symptoms are often mistakenly attributed to aging or stress. [34] Detailed neuropsychological testing can reveal mild cognitive difficulties up to eight years before a person fulfills the clinical criteria for diagnosis of Alzheimer's disease. [35] These early symptoms can affect the most complex activities of daily living. [36]

  9. Aging brain - Wikipedia

    en.wikipedia.org/wiki/Aging_brain

    The ability of an individual to demonstrate attenuated cognitive signs of aging despite an aging brain is called cognitive reserve. [22] [69] This hypothesis suggests that two patients might have the same brain pathology, with one person experiencing noticeable clinical symptoms, while the other continues to function relatively normally ...
