Vasomotor Symptoms: From 1 Different Sources
subjective sensations experienced by women around the time of the *menopause, often described as explosions of heat (hot flushes), mostly followed by profuse sweating and sometimes preceded by an undetermined sensation with waking at night. Objective signs are sudden reddening of the skin on the head, neck, and chest and profuse sweating. Physiological changes include peripheral vasodilatation, *tachycardia with normal blood pressure, and raised skin temperature with normal body temperature.
The description ‘vasomotor’ refers to control of the muscular walls of blood vessels, particularly ARTERIES, dilating or constricting their diameters. The vasomotor centre is a group of neurons (see NEURON(E)) in the MEDULLA OBLONGATA of the BRAIN; they receive messages from sensory receptors in the circulatory system, and engineer re?ex alterations in the heart rate and blood-vessel diameters in order to adjust the blood pressure. The centre also receives transmission from other parts of the brain enabling emotions – fear or anger – to in?uence blood pressure. The vasomotor centre operates through the vasomotor nerves of the SYMPATHETIC NERVOUS SYSTEM and the PARASYMPATHETIC NERVOUS SYSTEM.... vasomotor centre
Unpleasant physical and mental symptoms that occur when a person stops using a drug or substance on which he or she is dependent (see DEPENDENCE). The symptoms include tremors, sweating, and vomiting which are reversed if further doses are given. Alcohol and hard drugs, such as morphine, heroin, and cocaine, are among the substances that induce dependence, and therefore withdrawal symptoms, when stopped. Amphetamines and nicotine are other examples.... withdrawal symptoms
The experiences of a patient as communicated to a doctor, for example, pain, weakness, cough. They may or may not be accompanied by con?rmatory CLINICAL SIGNS.... clinical symptoms
Small nerve ?bres that lie upon the walls of blood vessels and connect the muscle ?bres of their middle coat with the NERVOUS SYSTEM. Through these nerves the blood vessels are retained in a state of moderate contraction. There are vasodilator nerves, through which are transmitted impulses that dilate the vessels, and, in the case of the skin vessels, produce the condition of blushing; there are also vasoconstrictor nerves which transmit impulses that constrict, or narrow, the blood vessels – as occurs on exposure to cold (see HYPOTHERMIA). Various drugs produce dilatation or contraction of the blood vessels, and several of the substances produced by ENDOCRINE GLANDS in the body have these effects: for example, ADRENALINE.... vasomotor nerves
(LUTS) symptoms occurring during urine storage, voiding, or immediately after. These include *frequency, *urgency, *nocturia, *incontinence, *hesitation, *intermittency, *terminal dribble, *dysuria, and *postmicturition dribble. These symptoms used to be known as prostatism. Sometimes they are due to benign prostatic hyperplasia (see prostate gland), but they may be due to *detrusor overactivity, excessive drinking, diuresis due to poorly controlled diabetes, or a urethral stricture.... lower urinary tract symptoms
(in psychiatry) symptoms of schizophrenia characterized by a deficiency in or absence of some aspect of functioning, such as social withdrawal, loss of initiative, and blunted affect. Compare positive symptoms.... negative symptoms
(in psychiatry) symptoms of schizophrenia characterized by a distortion of some aspect of functioning, such as delusions, hallucinations, or disordered speech. Compare negative symptoms.... positive symptoms
symptoms of *schizophrenia first classified by German psychiatrist Kurt Schneider (1887–1967) in 1938. First-rank symptoms were considered by Schneider to be particularly indicative of schizophrenia; they include all forms of *thought alienation, *delusional perception, *passivity, and third-person auditory *hallucinations in the form of either a running commentary or voices talking about the patient among themselves. Some schizophrenic patients never exhibit first-rank symptoms or only experience them in some psychotic episodes. They may also occur in *mania. Second-rank symptoms are common symptoms of schizophrenia but also often occur in other forms of mental illness. They include *delusions of reference, paranoid and persecutory *delusions, and second-person auditory hallucinations.... schneiderian first- and second-rank symptoms
adj. controlling the muscular walls of blood vessels, especially arteries, and therefore their diameter.... vasomotor
any nerve, usually belonging to the autonomic nervous system, that controls the circulation of blood through blood vessels by its action on the muscle fibres within their walls or its action on the heartbeat. The *vagus nerve slows the heart and reduces its output, but sympathetic nerves increase the rate and output of the heart and increase blood pressure by causing the constriction of small blood vessels at the same time.... vasomotor nerve
