Specific criteria have been developed based on computerized dynamic posturography (CDP) to assist clinicians in identifying patients with psychogenic balance problems (Cyr and Cevette, 1993; Cevette et al., 1995; Goebel et al., 1997; Gianoli et al., 2000). Patients with known spinocerebellar ataxia (SCA) meet several of the criteria for psychogenic balance problem and risk being misclassified a...

BACKGROUND Psychogenic or functional movement disorders (PMDs) pose a challenge in clinical diagnosis. There are several clues, including sudden onset, incongruous symptoms, distractibility, suggestibility, entrainment of symptoms, and lack of response to otherwise effective pharmacological therapies, that help identify the most common psychogenic movements such as tremor, dystonia, and myoclon...

The occurrence of de novo psychogenic seizures after epilepsy surgery is rare, and is estimated in 1.8% to 3.6%. Seizures after epilepsy surgery should be carefully evaluated, and de novo psychogenic seizures should be considered especially when there is a change in the ictal semiology. We report a patient with de novo psychogenic seizures after anterior temporal lobe removal for refractory tem...

Despite the substantial prevalence of psychogenic disorders (from 50% to 70% of patients who report to physicians of various specialities are treated for psychogenic, functional disorders), these disorders continue to be relatively poorly understood (Hamilton et al., 1996; Mace & Trimble, 1996). Psychogenic nonepileptic seizures (PNES) are one variety of psychogenic disorders. PNES are sudden c...

OBJECTIVE To assess whether surgery to reduce or control epileptic seizures is safe and effective in patients known to have additional psychogenic seizures. DESIGN We reviewed our computerized database of 1342 patients examined for epilepsy surgery and identified 13 patients with both epileptic and psychogenic seizures on whom postoperative outcome data were available. Data were gathered from...

In the majority of cases published between 1907 and 2014, FAS is due to a neurogenic etiology. Only a few reports about FAS with an assumed psychogenic origin have been published. The present article discusses the findings of a careful database search on psychogenic FAS. This review may be particularly relevant as it is the first to analyze the salient features of psychogenic FAS cases to date....

OBJECTIVES To review the clinical characteristics and associated features found in patients with psychogenic tremor. METHODS Ten-year retrospective review of charts of all patients and videotapes of fifty-one patients diagnosed by the senior author as having psychogenic tremor. RESULTS Seventy patients fulfilled the diagnostic criteria for clinically definite psychogenic tremors. Psychogeni...

Psychogenic fever is a stress-related, psychosomatic disease especially seen in young women. Some patients develop extremely high core body temperature (Tc) (up to 41°C) when they are exposed to emotional events, whereas others show persistent low-grade high Tc (37-38°C) during situations of chronic stress. The mechanism for psychogenic fever is not yet fully understood. However, clinical case ...

The wrong diagnosis of epilepsy is common. At referral epilepsy centers, psychogenic non-epileptic attacks are by far the most common condition found to have been misdiagnosed as epilepsy, with an average delay of 7-10 years. There are many "red flags" that can raise the suspicion of psychogenic non-epileptic attacks. Syncope is the second most common condition misdiagnosed as epilepsy, and it ...
