Older people often describe their headaches as starting with vague neck discomfort and eventually moving to the temples and forehead. These are muscle-tension headaches, by far the most common type in the elderly. Although cervical osteoarthritis often is at fault, depression can be a significant factor, patricularly when headaches are chronic. There is no sure cure for tension headache, and often, several of the many remedies-ethyl chloride spray, moist heat, massage, antidepressant drugs, analgesics, local anesthetics, etc.-must be tried before an effective one is found. But just as important to successful therapy are concern, compassion, and a willingness to listen on the part of the physician. True migraine headaches are rare in the elderly. More prevalent is the type of vascular headache associated with giant cell arteritis, which is severe and resistant to any form of analgesic except the strongest narcotics. Vascular headaches also may result from congestive heart failure (which produces venous congestion in the cranial cavity), transient ischemia, increased intracranial pressure, and a variety of metabolic disturbances.

Sixteen cases of vascular headache of the migraine type are referred in whom marked neurological manifestations occurred in a unilateral distribution as part of a migraine attack ("complicated migraine"). The neurologic disorders observed, in order of frequency, include 10 cases of motor hemiparesis, 3 cases of unilateral cerebellar syndrome, 1 case of sensory-motor hemiparesis and 1 case showing signs of the involvement of the motor nuclei of the bulb. The recovery of the motor, sensory, cerebellar and brainstem defects was very slow (average duration: 44.25 days; mode: 14 days) in twelve cases. Two patients showed residual neurological signs respectively after 1 and 7 years from the migraine attack. The patients histories indicate classic or common migraine with a relatively high frequency (80% of the patients experienced one or more crises per month). The most of cases (75%) were female patients. The patients, at time of the attack of complicated migraine, had a mean age years of 32. In ten cases first-grade relatives suffered from classic or common migraine; in no case was there any report of associated or complicated migraine among the relatives. In 4 of the 16 cases the CT scan showed an area of hypodensity consistent to the region of the brain expected to be suffering in view of the clinical type of neurological defect. The Authors take into consideration the controversial relation between complicated migraine with slow or incomplete resolution of neurologic signs and focal brain ischemia due to atherothrombotic infarct, pointing out that the present state of knowledge prevents the reaching of final conclusions.(ABSTRACT TRUNCATED AT 250 WORDS)

Characteristics of brain evoked activity were studied in patients with most frequent variants of secondary headaches: chronic posttraumatic headaches, cervicogenic headaches and vascular headaches in patients with arterial hypertension and chronic brain ischemia. The multimodal registration of evoked potentials (EP) (short-latency brainstem auditory, visual EPs to flash stimulation and cognitive EPs - P300) revealed signs of brainstem dysfunction, decrease of visual analyzer and diminished cognitive functions in most patients with secondary headaches. Based on results obtained, we can recommend a complex therapy of chronic secondary headaches with neuroprotectors and nootropics.
