Nocebo is very prevalent among neurological diseases resulting in low adherence and treatment outcome. We sought to examine the AEs following placebo administration in Randomized Controlled Studies (RCTs) for Alzheimer's Disease (AD). ⋯ In RCTs for AD one out of fifteen patients treated with placebo dropped out because of AEs and three out of five experienced AEs indicating that adherence and effectiveness may be adversely affected with additional implications for clinical practice. The principal implications of this paper are that nocebo deserves much.

The association between prediabetes and distal polyneuropathy (DPN) remains controversial. Here we test whether the prevalence of small fiber sensory distal polyneuropathy is increased in prediabetes. ⋯ Based on positive sensory and pain symptoms and QSTs, we did not find an increase in small fiber sensory DPN in prediabetes. Recognizing that obesity and diabetes mellitus are implicated in macro- and microvessel complications, physicians should encourage healthy living and weight loss in patients with prediabetes. In medical practice, alternate causes should be excluded before concluding that small fiber sensory distal neuropathy is secondary to prediabetes.

To differentiate MRI characteristics of optic neuritis associated with neuromyelitis optica (NMO) and relapsing remitting multiple sclerosis (RRMS). ⋯ Optic neuritis in NMO has a distinct pattern on MRI as compared with RRMS and can help differentiate these two neuroinflammatory diseases at presentation.

Trigeminal root entry zone abnormality on brain magnetic resonance imaging has been frequently reported in multiple sclerosis patients, but it has not been investigated in neuromyelitis optica patients. Brain magnetic resonance imaging of 128 consecutive multiple sclerosis patients and 46 neuromyelitis optica patients was evaluated. Trigeminal root entry zone abnormality was present in 11 (8.6%) of the multiple sclerosis patients and two (4.3%) of the neuromyelitis optica patients. The pontine trigeminal root entry zone may be involved in both multiple sclerosis and neuromyelitis optica.

To determine whether obstructive sleep apnea syndrome (OSAS) patients with mixed sleep apnea (MSA) have different clinical, polysomnographic, and continuous positive airway pressure (CPAP) titration findings compared to OSAS patients without MSA. ⋯ Severe OSA, older age, male sex, obesity, and daytime sleepiness were related to mixed-OSA. Complex sleep apnea, less optimal titration, and a higher titrated CPAP were also associated with MSA in OSAS patients.
