SCA3 symptoms include progressive motor decline caused by an atrophy of the cerebellum and brainstem. However, it was recently reported that SCA3 patients also suffer from the cerebellar cognitive affective syndrome. The majority of SCA3 patients exhibit cognitive decline and approximately half of them suffer from depression and anxiety. The necessity to find a combined therapy for both motor and cognitive deficits in a SCA3 mouse model is required for the development of SCA3 treatment. Here, we demonstrated that the SCA3-84Q transgenic mice exhibited anxiety over the novel brightly illuminated environment in the open field, novelty suppressed feeding, and light-dark place preference tests. Moreover, SCA3-84Q mice also suffered from a decline in recognition memory during the novel object recognition test. SCA3-84Q mice also demonstrated floating behavior during the Morris water maze that can be interpreted as a sign of low mood and aversion to activity, i.e. depressive-like state. SCA3-84Q mice also spent more time immobile during the forced swimming and tail suspension tests which is also evidence for depressive-like behavior. Therefore, the SCA3-84Q mouse model may be used as a model system to test the possible treatments for both ataxia and non-motor symptoms including depression, anxiety, and memory loss.<\/jats:p>","DOI":"10.1093\/hmg\/ddad179","type":"journal-article","created":{"date-parts":[[2023,10,20]],"date-time":"2023-10-20T17:53:47Z","timestamp":1697824427000},"page":"299-317","source":"Crossref","is-referenced-by-count":6,"title":["Memory
