Psychogenic “Jumpy Stump”

The jumpy janitor. Letter to an ethicist.

Psychogenic fever, functional fever, or psychogenic hyperthermia?

Psychogenic fever reflects a phenomenon where core body temperature is high (up to 41°C) or low-grade high (37-38°C) during either acute or chronic stress. Underlying mechanisms are distinct from infection-induced fever and involve the central and sympathetic nervous systems. Psychogenic fever appears a complex psychological, physiological and endocrinological phenomenon.

Control of autophagy initiation by phosphoinositide 3-phosphatase Jumpy.

The majority of studies on autophagy, a cytoplasmic homeostasis pathway of broad biological and medical significance, have been hitherto focused on the phosphatidylinositol 3-kinases as the regulators of autophagy. Here, we addressed the reverse process driven by phosphoinositide phosphatases and uncovered a key negative regulatory role in autophagy of a phosphatidylinositol 3-phosphate (PI3P) ...

Psychogenic pain

Unless the patient has reasons for ‘malingering’ – the symptoms are simulated for compensation or litigation motives – pain is always indicative of some degree of dysfunction. In most instances, the dysfunction is physical. Sometimes, however, the pain is devoid of any organic basis. If the patient has an unconscious belief in the reality of the symptoms, a psychogenic disorder is likely. The p...

Psychogenic amnesia.

Time- and content-based memory systems are briefly described so that their importance for a refined analysis of memory disturbances becomes evident. These memory systems are then related to their brain instantiation, emphasizing that there are limbic circuits for encoding different forms of memories, largely cortical networks for memory storage, and a combined temporofrontal network acting to t...
