Clarifying the Cause and Treatment of Paroxysmal Hypertension (Pseudopheochromocytoma)

Abstract

Purpose of review To review the clinical characteristics of paroxysmal hypertension (pseudopheochromocytoma), its previously unsuspected cause, and effective treatment approaches. Recent findings Patients with paroxysmal hypertension experience recurrent, sudden, unprovoked, symptomatic, and severe elevations of blood pressure that occur independently of current stress or perceived emotional distress. Recent findings point to a previously unsuspected psychosomatic etiology, linked in most to a past history of abuse, trauma, or prolonged severe stress, often with repression of pertinent emotions, or to a repressive coping style. Consistent with this understanding, treatment with an antidepressant is thus far the only pharmacologic intervention demonstrated to be effective in preventing recurrent paroxysms, and is effective in most patients. Other treatment approaches are discussed, including medications to acutely lower blood pressure during paroxysms, and, in some cases, the possibility of emotional healing. Recent findings indicate that paroxysmal hypertension is a psychosomatic disorder frequently linked to a past history of trauma or prolonged severe stress, usually with longstanding repression of pertinent emotions. Data strongly encourage treatment with an antidepressant in patients with recurrent or severe paroxysms. Further studies are needed.
