Reproducibility of cortical response modulation induced by intermittent and continuous theta-burst stimulation of the human motor cortex.

Brain Stimul 2021 Jun 11. Epub 2021 Jun 11.

Berenson-Allen Center for Noninvasive Brain Stimulation, Department of Neurology, Beth Israel Deaconess Medical Center, Boston, MA, USA; Department of Neurology, Harvard Medical School, Boston, MA, USA. Electronic address:

Background: Over the past decade, the number of experimental and clinical studies using theta-burst-stimulation (TBS) protocols of transcranial magnetic stimulation (TMS) to modulate brain activity has risen substantially. The use of TBS is motivated by the assumption that these protocols can reliably and lastingly modulate cortical excitability despite their short duration and low number of stimuli. However, this assumption, and thus the experimental validity of studies using TBS, is challenged by recent work showing large inter- and intra-subject variability in response to TBS protocols.

[Cognitive reserve, one of the determinants of the progression of Alzheimer's disease].

Geriatr Psychol Neuropsychiatr Vieil 2021 Jun 3. Epub 2021 Jun 3.

Pôle de gériatrie, CM2R, Hôpitaux universitaires de Strasbourg, France, Laboratoire ICube, UMR 7357, Université de Strasbourg et CNRS, Strasbourg, France.

To appraise the validity of the Yaakov Stern's theory, which postulates that the first cognitive deficits of Alzheimer's disease are delayed in patients with high cognitive reserve, compared to those with low cognitive reserve, but is subsequently associated with faster cognitive decline when cerebral lesions have reached some degree of severity. A retrospective study of 318 patients with Alzheimer's disease without associated cerebral disorders, was performed in the Memory Clinic of the University Hospital of Strasbourg. The patients were divided into 5 groups according to the degree of cognitive reserve assessed by the level of education (primary, middle school, intermediary, high school and higher education).
