Objective: To evaluate the effect of King's Brain pills (Compound Chinese ginseng extract from herbs) on the treatment and the delaying of memory decline in the elderly with mild cognitive impairment (MCI) in a community by a year follow-up of neuropsychology.
Method: 75 patients with MCI were selected from Beixinqiao community of Beijing by a cutoff score of 0.0/0.5 on CDR and were randomly assigned into a treatment group (n = 30 cases), given 4 pills of a compound Chinese ginseng extract (King's Brain) with 2 placebo tablets, and a positive control group (n = 30 cases), given 2 tablets of Piracetam with 4 placebo tablets, as well as a placebo group (n = 15 cases), given a placebo of 4 tablets and 2 pills. All subjects took this medication 3 times a day for 3 months. Single-blind and double-moulding control were used in this study. At a baseline and a middlepoint (after 3 months), and a follow-up end (one year later) following a three months of medication therapeutics, all subjects were assessed using a battery consisting of MMSE and 5 memory items on BNPT battery.
Result: In the treatment group, MMSE score 27.50 +/- 1.68 was increased to 28.27 +/- 1.70 after 3 months but decreased to 26.90 +/- 1.90 after one year of the treatment. However, the latter score was higher than that in a placebo group 26.33 +/- 1.03 (P < 0.05). Verbal Learning Test score was significantly increased from 68.73 +/- 28.74 at baseline to 87.33 +/- 29.78 at follow-up point in the treatment group, which was significantly higher than that in the placebo group (P < 0.01). The total score of memory items on BNPT battery was significantly increased from 78.23 +/- 28.98 at baseline to 93.53 +/- 35.56 at follow-up point in the treatment group, higher than that in Piracetam group (P < 0.05) and the placebo group (P < 0.01).
Conclusion: Both King's Brain spills and piracetam tablets have protective effect on cognitive and memory decline in elderly with MCI.

Previous research suggests that emotional prosody perception is impaired in neurodegenerative diseases like Alzheimer's disease (AD) and primary progressive aphasia (PPA). However, no previous research has investigated emotional prosody perception in these diseases under non-ideal listening conditions. We recruited 18 patients with AD, and 31 with PPA (nine logopenic (lvPPA); 11 nonfluent/agrammatic (nfvPPA) and 11 semantic (svPPA)), together with 24 healthy age-matched individuals.

Introduction: Neuropsychiatric symptoms (NPSs) are common in dementia with Lewy bodies (DLB) but their neurobiological mechanisms are poorly understood.
Methods: NPSs and cognition were assessed annually in participants (DLB n = 222; Alzheimer's disease [AD] n = 125) from the European DLB (E-DLB) Consortium, and plasma phosphorylated tau-181 (p-tau181) and p-tau231 concentrations were measured at baseline.
Results: Hallucinations, delusions, and depression were more common in DLB than in AD and, in a subgroup with longitudinal follow-up, persistent hallucinations and NPSs were associated with lower p-tau181 and p-tau231 in DLB.

Schizophrenia (SCZ), bipolar (BD) and major depression disorder (MDD) are severe psychiatric disorders that are challenging to treat, often leading to treatment resistance (TR). It is crucial to develop effective methods to identify and treat patients at risk of TR at an early stage in a personalized manner, considering their biological basis, their clinical and psychosocial characteristics. Effective translation of theoretical knowledge into clinical practice is essential for achieving this goal.

Transcranial Magnetic Stimulation-Electroencephalography (TMS-EEG) is a non-operative technique that allows for magnetic cortical stimulation (TMS) and analysis of the electrical currents generated in the brain (EEG). Despite the regular utilization of both techniques independently, little is known about the potential impact of their combination in neurosurgical practice. This scoping review, conducted following PRISMA guidelines, focused on TMS-EEG in epilepsy, neuro-oncology, and general neurosurgery.
