Improvement of Memory with Transcranial Electrical Brain Stimulation in Patients with Alzheimer’s Disease
The authors showed that gamma frequency transcranial alternating current stimulation targeting the precuneus in patients with Alzheimer’s disease improved measures of immediate and delayed verbal memory as well as associative memory for faces. Additionally, neurophysiological measurements of cholinergic transmission improved. Apolipoprotein E genotype and baseline cognitive performance were correlated with treatment response. Memory improvement was correlated both with increases in gamma frequency power in posterior cortical regions and spatial overlap between the modeled electric field distribution and the precuneus target site.

Neurodegenerative Ataxia: Improvement in Motor and Cognitive Outcomes with Cerebello-Spinal Stimulation
Concurrent cerebellar and spinal stimulation with a transcranial direct current stimulation device resulted in improvement of both motor and cognitive functions in patients with several different forms of neurodegenerative ataxia.

Deep Brain Stimulation of the Cortico-Striato-Thalamo-Cortical Network May Be an Option for Refractory OCD
Deep brain stimulation can be a treatment option for refractory obsessive-compulsive disorder, but the results are not significantly better than lesioning procedures. Small sample sizes, diverse targets of stimulation, and inconsistencies in rating scales are limiting factors in the studies of this modality.

Electrical Brain Stimulation for Primary Progressive Aphasia
In this pilot study, transcranial direct current stimulation appeared to improve some aspects of verbal object identification and naming in a small number of patients with primary progressive aphasia.
