For example, acetylcholinesterase inhibitors galantamine and memantine, which are typically prescribed for Alzheimer’s disease patients, are also actively explored in autism (Maire and Wurtman, 1984; Hertzman, 2003; Nicolson et al., 2006; Ghaleiha et al., 2014; Rossignol and Frye, 2014; Rahman et al., 2018). Here, ACHE is linked to early-onset autosomal dominant Alzheimer disease.
