Synonyms: Alzheimer disease; Alzheimers dementia; Definition: A tauopathy that is characterized by memory lapses, confusion, emotional instability and progressive loss of mental ability and results in progressive memory loss, impaired thinking, disorientation, and changes in personality and mood starting and leads in advanced cases to a profound decline in cognitive and physical functioning and is marked … A new study by scientists at VIB and KU Leuven identifies the … The forebrain then divides into anterior and posterior regions, which are referred to as the telencephalon and diencephalon. Their ability to regenerate neurons comes from progenitor cells. -, Hamley IW. Effects of linarin on treating AD zebrafish dyskinesia and AChE inhibition were compared with donepezil (DPZ) which was used as a positive control drug. We have created the world’s first … The emerging use of the zebrafish model in neurological and neurodegenerative human diseases (such as PD, autism, Huntington’s disease, and Alzheimer’s disease) was described by Xi et al. Washington, Aug 20 (ANI): Zebrafish, which are originally from India, but also a popular aquarium fish, has helped researchers to obtain a deeper insight into the Alzheimer's disease. Neurotoxicol Teratol. 2020 Feb;15(2):285-292. doi: 10.4103/1673-5374.265566.
