Studies of CSF 5-HIAA in Depression and Suicidal Behaviour
1981The present series of studies of CSF monoamine metabolites support the hypothesis of a role for serotonin in depressive illness, insofar that depressed patients have slightly lower CSF 5-HIAA concentrations than normal controls. Apparently a normal association between CSF 5-HIAA and platelet MAO activity is disrupted in depression.

Intraspinal Pressure Influences CSF Disposition of Tryptophan and 5-HIAA
Neuropsychobiology, 2001Cerebrospinal fluid (CSF) concentrations of monoamine compounds are influenced by factors such as age, gender, height, body weight, tapping time, and atmospheric pressure. We have now examined the role of intraspinal pressure. Thirteen male volunteers underwent lumbar puncture in the right decubitus position without preceding strict bed rest.

Neurology, 1979 CSF 5-HIAA correlates with neuroticism in depressed patients
Journal of Affective Disorders, 1999To examine for relationships between neurotransmitters and personality.27 depressed patients had cerebrospinal fluid (CSF) monoamine metabolites measured and completed the Eysenck Personality Questionnaire (EPQ).CSF concentrations of the serotonin metabolite 5-hydroxyindoleacetic acid (5-HIAA) correlated significantly with EPQ neuroticism scores ...

Altered CSF 5-HIAA Disposition in Pathologic Male Gamblers
CNS Spectrums, 1999AbstractPrevious reports concerning the cerebrospinal fluid (CSF) of pathologic gamblers have described disturbed norepinephrine and dopamine (but not serotonin) functioning in the central nervous system. We analyzed neurotransmitter metabolites in two consecutive 6-mL samples of CSF obtained from 10 pathologic male gamblers punctured at the L4-5 level

Cholesterol, CSF 5-HIAA, violence and intent in suicidal men
Psychiatry Research, 2010Associations between suicide, violent behaviour and both hypocholesterolaemia and low 5-hydroxyindolacetic acid (5-HIAA) in the cerebrospinal fluid (CSF) have been suggested. The relationships between lipids, the serotonergic system, suicidal and aggressive behaviors are complex.

On the Clinical Significance of Serotonin and 5-HIAA in Body Fluids
1981Changes in serotonin (5-hydroxytryptamine, 5-HT) metabolism have been postulated in several psychiatric disorders. The main research efforts, however, have been focussed on the serotonin hypotheses of manic-depressive illness and schizophrenia.

CSF 5-HIAA, cortisol and DHEAS levels in suicide attempters
European Neuropsychopharmacology, 2013The serotonin system and the hypothalamic-pituitary-adrenal (HPA) axis are involved in the biological vulnerability to suicidal behaviour. Altered levels of dehydroepiandrosterone (DHEA) and its sulphate ester DHEAS have been reported in neuropsychiatric conditions.

5-HIAA and HVA in CSF in patients with idiopathic pain disorders
Biological Psychiatry, 1987Patients with idiopathic pain syndromes were compared with healthy volunteers and with patients suffering from chronic pain syndromes of neurogenic origin, with respect to the concentrations of the metabolites 5-hydroxy-indole-acetic acid (5-HIAA) and homovanillic acid (HVA) in cerebrospinal fluid (CSF).

CSF testosterone and 5-HIAA correlate with different types of aggressive behaviors
Biological Psychiatry, 1996We studied the potential roles of testosterone and serotonin in various forms of aggressive and violent behaviors by measuring each biochemical and behaviour in free-ranging adolescent male nonhuman primates. Our results showed that (1) CSF free testosterone concentrations were positively correlated with overall aggressiveness, but not with measures of
