| sick headache | <disease> An often familial symptom complex of periodic attacks of vascular headache, usually temporal and unilateral in onset, commonly associated with irritability, nausea, vomiting, constipation or diarrhoea and often photophobia, attacks are preceded by constriction of the cranial arteries, usually with resultant prodromal sensory (especially ocular) symptoms and commence with the vasodilation that follows. Origin: Gr. Hemikrania = an affection of half of the head (18 Nov 1997) |
|---|---|
| spinal headache | A headache that can occur after a lumbar puncture is performed. Patients who lie flat on their stomach for one hour immediately after lumbar puncture, followed by 12 hours on their back, have a decreased incidence of spinal headaches. (27 Sep 1997) |
| nodular headache | Radiating pain in the head accompanied by nodular swellings in the splenius, frontalis, trapezius, and other muscles. (05 Mar 2000) |
| symptomatic headache | A headache secondary to another organic condition. Synonym: reflex headache. (05 Mar 2000) |
| organic headache | Headache due to intracranial disease. (05 Mar 2000) |
| tension headache | <neurology> A benign form of headache that results from the painful spasm (muscle tightness) and inflammation of muscles of the head and neck. Tension headache is one of the most common forms of headache. Spasm and contraction of the head and neck muscles may occur in response to fatigue, overuse, eye strain, excessive smoking, stress, anxiety or depression. Sleeping in an abnormal position or prolonged work involving immobilisation of the neck in one position (typing, computers, etc.) are considered common triggers. Exercising and stretching the muscles of the head and neck can reduce the occurrence of muscle tension headaches. (13 Jan 1998) |
| fibrositic headache | Headache centreed in the occipital region due to fibrositis of the occipital muscles; tender areas are present and, commonly, tender nodules are found in the scalp in the lower occipital region. (05 Mar 2000) |
| action current | An electrical current induced in muscle fibres when they are effectively stimulated; normally it is followed by contraction. (05 Mar 2000) |
| alternating current | Electrical current which alternates direction periodically. (For instance, household electric current is AC alternating at 60 oscillations/sec (60 Hertz) in the United States, and 50 Hertz in many other countries.) Acronym: AC (09 Oct 1997) |
| anodal current | A current produced in tissues under the anode when the circuit is closed. (05 Mar 2000) |
| ascending current | The direction of current flow in a nerve when the anode is placed peripheral to the cathode, in contrast to descending current; the convention used is that current flows from positive to negative. Synonym: centripetal current. (05 Mar 2000) |
| axial current | The central rapidly moving portion of the bloodstream in an artery. (05 Mar 2000) |
| bootstrap current | <radiobiology> Currents driven in toroidal devices by neo-classical diffusion. They may amount to a substantial fraction of the net current in a tokamak reactor, thus lengthening the pulse time or decreasing the power needed for current drive. (09 Oct 1997) |
| calcium current | Inflow of calcium ions through specific calcium channels. Critically important in release of transmitter substance from presynaptic terminals. (18 Nov 1997) |
| galvanic current | See: direct current, galvanism. (05 Mar 2000) |
