The cholinergic network affects various cellular functions including neurotransmission, and immune reactions. In Myasthenia Gravis (MG), diagnosis and symptomatic therapy are based on cholinergic modulation by acetylcholinesterase inhibitors (AChEI). In Alzheimer's disease (AD) a neurodegenerative disorder associated with inflammatory pathology, cholinergic systems cell loss occurs early. Treatments with special AChEI enhance cholinergic transmission and may act as anti-inflammatory agent via immunocompetent cells expressing alpha-7 acetylcholine receptor (AChR). In Multiple Sclerosis (MS) an inflammatory T-cell-mediated disease, demyelination and neurodegeneration follow neuroinflammation. MS treatment includes anti-inflammatory and immunomodulatory drugs. AChEI can induce cholinergic up-regulation with subsequent effect on neuroinflammation via alpha-7-AChR expressing cells. These effects are additional to the cognitive benefit induced by AChEI.

Background: Alzheimer's disease (AD) is a chronic, progressive neurodegenerative disorder characterized by cognitive decline, memory loss, and impaired reasoning. It is the leading cause of dementia in older adults, marked by the pathological accumulation of amyloid-beta plaques and neurofibrillary tangles. These pathological changes lead to widespread neuronal damage, significantly impacting daily functioning and quality of life.

Background: Evidence on antidementia drugs (ADD) use in developing countries, where accessibility to ADD is challenging, is limited. Our aim was to examine prescribing patterns, factors, and outcomes associated with the early-ADD use (within 3 months from diagnosis) in people with dementia.
Methods: A retrospective cohort study included individuals aged ≥ 60 years with dementia from three hospitals in Thailand between 2015 and 2020.

Galantamine plays a crucial role in the management of brain disorders. In this study, a series of galantamine analogues were designed, synthesized and evaluated as potential therapeutic agents for Alzheimer's disease (AD). Compound C2, a dual inhibitor of cholinesterase, was obtained by introducing a benzylpyridine ring to the hydroxyl group of galantamine.

The abnormal expression of acetylcholinesterase (AChE) is linked to the development of various diseases. Accurate determination of AChE activity as well as screening AChE inhibitors (AChEIs) holds paramount importance for early diagnosis and treatment of AChE-related diseases. Herein, a fluorescent and colorimetric dual-channel probe based on gold nanoclusters (AuNCs) and manganese dioxide nanosheets (MnO NSs) was developed.
