We report a 71-year-old woman with tactile hallucinations induced by trihexyphenidyl. Six and a half months after starting trihexyphenidyl, this patient with Parkinson's disease complained of tactile hallucinations, mainly on her feet, at night while in bed. Four days after stopping the medication, the sensations disappeared. Although tactile hallucinations induced by trihexyphenidyl are rare, it should be noted that the condition can be induced by anti-Parkinson's disease drugs.

Background: Etomidate has been observed to precipitate myoclonus in patients undergoing induction of general anaesthesia. This study was designed to investigate the effect of pretreatment with a small dose of esketamine on the incidence of myoclonus induced by etomidate.
Methods: One hundred adult patients, who were scheduled to undergo selective operations with general anesthesia, were randomly divided into two groups, with one group receiving esketamine (Group E) and the other receiving normal saline (Group C).

Presenting symptoms of sporadic Creutzfeldt-Jakob disease (sCJD) are variable, and as imaging and EEG may be normal in the early to middle stages of the disease process, serial testing is vital when there is clinical suspicion for sCJD. We present a case of probable Heidenhain variant of sCJD (HvCJD) with notable rapid progression. A 72-year-old woman presented with neurological decline following new-onset visual changes.

When we vocalize, our brain distinguishes self-generated sounds from external ones. A corollary discharge signal supports this function in animals; however, in humans, its exact origin and temporal dynamics remain unknown. We report electrocorticographic recordings in neurosurgical patients and a connectivity analysis framework based on Granger causality that reveals major neural communications.

Article Synopsis
- Contrast-induced encephalopathy (CIE) is a rare but serious complication after coronary angiography, often presenting as transient cortical blindness; however, this case reports the first instance of CIE accompanied by visual and auditory hallucinations.
- An 80-year-old female patient experienced confusion and hallucinations following an elective coronary procedure, after complications were encountered during the angiography; stroke was initially suspected but ruled out through MRI.
- The patient was diagnosed with CIE and treated with sedation and quetiapine for her hallucinations, ultimately leading to the resolution of her symptoms within five days.
