Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain stimulation method that has been suggested as a possible treatment method for cognitive impairment in patients with Alzheimer's Disease (pwAD), similar to multidomain cognitive training (CT). The effectiveness, however, of combining these techniques for pwAD remains controversial due to the variability in rTMS parameters, differences in CT protocol designs-many of which neglect the language domain-and the inclusion of patients at various stages of Alzheimer's Disease (AD) and with different types of dementia. The current review aims to evaluate the cognitive benefits of combining rTMS with CT, including language training, for individuals with mild to moderate AD.

Article Synopsis
  • - The study aimed to analyze the cognitive changes over a decade in older adults (60+) who are not yet diagnosed with dementia but are at risk for developing Alzheimer's disease (AD), Lewy body dementia (LBD), vascular dementia (VD), and frontotemporal dementia (FTD).
  • - Researchers assessed cognitive abilities annually, focusing on various skills like memory, verbal fluency, and executive functions, involving 3,343 participants who developed AD and others for LBD, FTD, and VD.
  • - Findings showed distinct cognitive decline patterns; for instance, those with AD faced memory issues earlier than those with VD and LBD, while verbal fluency and naming skills helped differentiate FTD from other dementia types. *

Previous studies have reported that widely used tests for aphasia identification are unable to detect the subtle language deficits of left hemisphere brain damaged (LHBD) individuals. Similarly, the language disorders of individuals with right hemisphere brain damage (RHBD) usually remain undetected, due to the lack of any specialized test for the evaluation of their language processing skills. The aim of the present study was to evaluate the language deficits of 80 individuals suffering from the effects of either a LHBD or RHBD stroke, who were diagnosed as having no aphasia or language deficits based on the application of Boston Diagnostic Aphasia Examination.

Background: The role of temporal lobe epilepsy (TLE) in determining personality traits and neurobehavioral symptoms, collectively known as the interictal behavioral syndrome (also known as Geschwind syndrome or "Gastaut-Geschwind syndrome"), as well as the syndrome's association with the particular artistic expression of many epileptic litterateurs are well known in neurology and psychiatry. A deepening of emotionality along with a serious, highly ethical, and spiritual behavior have been described as positive personality changes among patients with chronic mesial-TLE.

Objectives: Our narrative-based clinical hypothesis aims at contributing to the ongoing debate on the association between TLE and artistic expression, as well as the latter's supposed implication for epileptology in general and the neuropsychology of epilepsy in particular.
