Clinical lycanthropy is defined as a rare psychiatric syndrome that involves a delusion that the affected person can transform into, has transformed into, or is a non-human animal. Its name is connected to the mythical supranatural stories of lycanthropy, in which humans are said to physically shape shift into wolves. According to suggested diagnostic criteria for lycanthropy, either a delusional belief in current or past transformation or behavior that suggests a person thinks of himself as transformed is considered evidence of clinical lycanthropy. Hereby we present a case of clinical lycanthropy in a male patient reporting moments of feeling himself as a wolf and behaving in a manner that resembles wolf behavior, for example howling and growling.

Patients with anxiety spectrum disorders are a highly heterogeneous group, requiring new therapeutic strategies and individualized treatment monitoring. Today, there is a growing interest for implementing biological approaches to clinical practice in psychiatry. Quantitative EEG is an excellent tool in this regard, though it has been widely underestimated when compared to recent neuroimaging techniques. In this case series, we presented four cases with a different diagnosis of anxiety spectrum disorder and evaluated their qEEG changes before and after the treatment. In addition, we also calculated the so-called EEG cordance values as an index of cerebral perfusion and cingulate cortex activity. According to the results, there appears to be an increase in the frontal beta and theta band in our cases, which has responded to treatment. In regards to the cordance values, we found that there was a reduction in the prefrontal regions up to %38 percent following the treatment. Based on previous studies, this may also indirectly suggest reduction in the cingulate cortex activity. The possible implications of these findings were discussed. Taken together, this case series highlighted the potential use of qEEG power values, normative z-scores and cordance values in treatment response monitoring of anxiety spectrum disorders.

Creutzfeldt Jakob Disease is an incurable and invariably fatal degenerative brain disease. Sporadic and variant forms of the disease can be observed among patients. We report on a patient for calling attention to clinical features and laboratory findings of CreutzfeldtJakob Disease and the psychiatric prodromal symptoms. This case demonstrates that psychiatric symptoms may also be a presenting symptom of Creutzfeldt-Jakob Disease and this diagnosis should be considered when rapid deterioration in cognition is observed with presence of psychiatric and neurological symptoms.

Trichotillomania is a psychiatric disorder that involves repetitive hair pulling to the point of apparent loss. No approved treatment algorithm is available for trichotillomania. We present a case report of a 28-year-old female diagnosed as trichotillomania, with complaints of recurrent hair pulling resulting in noticeable hair loss. She was treated with Habit Reversal Training and a selective serotonin reuptake inhibitor (sertraline) over a period of 6 weeks. Habit reversal training includes self-monitoring, awareness training, competing response training, and homework assignments. The aim of this case report is to provide a brief description of habit reversal training, which is unfamiliar to many professionals.
