Repetitive transcranial magnetic stimulation (rTMS) has been explored as an intervention in typical amnestic Alzheimer's Disease (AD). However, its effects on episodic and associative memory in atypical forms of AD are less known. Posterior cortical atrophy (PCA) is primarily characterized by visuospatial and visuoperceptual symptoms, although significant episodic memory deficits are often...

Neuropsychiatry is a transdisciplinary field at the intersection of neuroscience, psychiatry, neurology, and humanities. Despite this strategic position, a comprehensive framework is still needed to bridge these domains. This review examines the historical evolution of how neurological, mental, and neuropsychiatric symptoms have been conceptualized, from antiquity to contemporary models, using...
To test for sex differences in the impact of cannabis use on decision-making and brain correlates, we employed cortical thickness (CT) analysis of brain regions involved in intertemporal decision-making namely bilateral orbitofrontal cortex(OFC) and insula in young adult nondependent cannabis-users(CU) and non-users(NU) and their scores on delay discounting task. Neuroimaging analyzes of...
Decision-making (DM) impairments are important predictors of cannabis initiation and continued use. In cannabis users, how decision-making abnormalities related to structural and functional connectivity in the brain are not fully understood. We employed a three-method multimodal image analysis and multivariate pattern analysis (MVPA) on high dimensional 7 tesla MRI images examining functional...
