Psychogenic dizziness is defined as recurring or persistent symptoms of balance dysfunction, inconsistent with organic vestibular disease as determined by history, clinical examination and pertinent investigations, and consistent with emotional origin. Of 1,335 patients seen in our dizziness clinic between January 1988 and August 1991, psychogenic dizziness was diagnosed in 180 (13.5%) patients. There were 67 men and 113 women aged from 12 to 77 years (mean age 40.2 years). The characteristics of psychogenic dizziness are: (1) continuous dizziness for long periods of time; (2) younger patients; (3) predominant female; (4) associated symptoms of panic attack, such as headache, breathlessness, nausea, sleep disturbance, paresthesias, anxiety and palpitation; (5) symptoms of aggravation due to stressful life events; (6) normal neurotological bedside examination; (7) hyperventilation reproduced accurately. The electronystagmographic results of 74 patients show normal bithermal caloric responses in 47 patients (63.5%), caloric hyperactivity in 21 patients (28.4%), canal paresis in four patients (5.4%), canal paresis with directional preponderance in two patients (2.7%), large random voluntary eye swings or severe blinking in 35 patients (47.3%), and spontaneous nystagmus (slow phase velocity < 6.5 degrees/s) in four patients (5.4%). There were 31 patients who consulted psychiatrists with diagnoses of anxiety (51.6%), depression (16.1%), insomnia (12.9%), psychosomatic disorder and adjustment disorder. Treatment of patients with psychogenic dizziness must be directed at the underlying anxiety. Psychiatric consultation is necessary.

Mild traumatic brain injury (TBI) encompasses the postconcussion syndrome characterized by symptoms that include a variety of physical symptoms as well as cognitive and behavioral impairments. The focus of this discussion is on the medical management of posttraumatic headaches, posttraumatic seizures, dizziness, auditory impairments, anosmia, tremor, paraspinal pain, and visual symptoms. Adjustment disorders with disturbances of affect and emotion lability also may accompany mild TBI. All of these conditions may be approached with medications or a variety of therapy techniques or both. The approach to concussion in sports-related injuries is also reviewed.

A 53-year-old woman with depressive symptoms and sleep problems, diagnosed as adjustment disorder with depressive reaction (ICD-10, F43.2), was treated with mirtazapine at a dose of 30 mg/day for a period of 10 weeks. In view of an imminent surgical intervention, the medication was than abruptly stopped. On the second day after discontinuation of mirtazapine, the patient developed a typical panic attack crisis with symptoms of palpitations, dyspnoea, retro-sternal pain, dizziness and nausea, blurred vision, anguish and fear of dying. During the next 5 days the patient suffered from severe, similar attacks recurring every 1-2 h, with each attack lasting about 20 min. Upon hospitalization and minor surgical intervention, the frequency and severity of symptoms regressed progressively, but the patient remained, with about one attack per week, not symptom free until the restitution of mirtazapine treatment at a dose of 30 mg/day. After re-introduction of mirtazapine panic attacks vanished, and during the entire follow-up period the patient remained symptom free. This case illustrates the risk of abrupt withdrawal of mirtazapine and indicates that, even after a medium-long therapy (10 weeks) with mirtazapine, progressive tapering-off of medication is advisable.
