AI Article Synopsis
- Cognitive toxicity from cranial radiation significantly affects the quality of life for brain tumor survivors and is a key limitation of radiation therapy.
- Recent studies utilizing neuropsychological assessments and advanced imaging techniques have pinpointed critical brain areas related to this injury, aiding in better clinical diagnosis.
- While there isn't a proven effective treatment yet, strategies like sparing the hippocampus and using memantine show promise in mitigating cognitive damage and improving patient outcomes.
Article Abstract
Cognitive toxicity induced by cranial radiation is one of the most important limitations of radiation therapy and has a significant impact on brain tumor survivors' quality of life. This review comprehends an up to date of recent studies including complete neuropsychological battery and/or advanced neuroimaging techniques. These studies identified critical anatomical and/or functional brain areas related to radiation-induced brain injury, thus improving clinical and radiological diagnosis. Pathophysiological mechanisms underlying cognitive toxicity are complex and involve different cell lines and molecules. Although there is no currently therapeutic strategy that has a demonstrated efficacy, several studies including sparing of hippocampus or the use of memantine are quite promising. A better knowledge of the characteristics of cognitive toxicity induced by cranial radiation, will help us to identify patients who will benefit from treatment and also to examine new therapeutic targets in order to improve patients' quality of life.

Dementia is a group of diseases, including Alzheimer's disease (AD), vascular dementia, Lewy body dementia, frontotemporal dementia, Parkinson's disease dementia, metabolic dementia and toxic dementia. The treatment of dementia mainly includes symptomatic treatment by controlling the primary disease and accompanying symptoms, nutritional support therapy for repairing nerve cells, psychological auxiliary treatment, and treatment that improves cognitive function through drugs. Among them, drug therapy to improve cognitive function is important.

Serious neurological disorders were associated with cadmium toxicity. Hence, this research aimed to investigate the potential neuroprotective impacts of the ethanolic extracts of Citrus aurantium unripe fruits and leaves (CAF and CAL, respectively) at doses 100 and 200 mg/kg against cadmium chloride-provoked brain dysfunction in rats for 30 consecutive days. HPLC for natural pigment content revealed that CAF implied higher contents of Chlorophyll B, while the CAL has a high yield of chlorophyll A and total carotenoid.

Background: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is one of the most common inherited cerebral small vessel diseases caused by the NOTCH3 gene mutation. This mutation leads to the accumulation of NOTCH3 extracellular domain protein (NOTCH3) into the cerebral arterioles, causing recurrent stroke, white matter lesions, and cognitive impairment. With the development of gene sequencing technology, cysteine-sparing mutations can also cause CADASIL disease, however, the pathogenicity and pathogenic mechanisms of cysteine-sparing mutations remain controversial.

Objective: Globally, in 2022, 30,871 children were diagnosed with CNS-tumors. Many have been treated with radiotherapy, and a significant number suffer from chronic late effects, including fatigue. This study aims to investigate previous research on the impact of cancer-related fatigue for neurocognitive function that can be related to radiotherapy in patients who have undergone primary brain radiotherapy before the age of 18.

Background: In the inflammatory process of multiple sclerosis (MS) several toxic waste products are generated. The clearance of these products might depend on the glymphatic system; however, it's preserved function in MS is uncertain. Recently, it was suggested that this 'waste clearance' system can be examined by measuring the diffusion along the perivascular space (ALPS) index.
