The Reliability of Urinary 5-HIAA Levels
Neuropsychobiology, 1994Examination of the serotonin metabolite, 5-hydroxyindoleacetic acid (5-HIAA), in the urine of psychiatry patients has generally not been used because the reliability of urinary 5-HIAA levels has been questioned. Thirty-seven generalized anxiety disordered patients collected two consecutive urines for measurement of 5-HIAA. The correlation of the 5-HIAA

Hydrocephalus: 5-HIAA and HVA in the Cerebrospinal Fluid
2021The choroid plexus form cerebrospinal fluid (CSF) within four ventricles the brain. The composition of CSF is very similar to the of the brain’s extracellular, and its composition depends on filtration and diffusion from the blood. Few conditions cause CSF volume and pressure to fall below normal (dehydration may be one), but many conditions can cause ...

Cholesterol and CSF 5-HIAA in attempted suicide
Journal of Affective Disorders, 2010Low serum cholesterol has been linked to suicide and violent behaviour. The same kind of associations has been reported regarding low levels of 5-hydroxyindolacetic acid (5-HIAA) in the cerebrospinal fluid (CSF) and suicidal behaviour. The hypothesis of the link between serum cholesterol and suicide incorporate serotonin.

Developmental Brain Research, 1985
Sprague-Dawley rat pups were deprived of food and/or the dam in experiment 1 for 24 h prior to sacrifice at 4, 10, 16 and 22 days postnatally and analysis of 5-HT, 5-HIAA and 5-HIAA/5-HT ratios in cortex, forebrain minus cortex, and brainstem. Deprivation was observed to increase indoles and their ratio early in life, with the most pronounced effects ...

5-HIAA in the Cerebrospinal Fluid
Archives of General Psychiatry, 1976The incidence of suicidal acts was studied in 68 depressed patients and related to the level of 5-hydroxyindoleacetic acid (5-HIAA) in the cerebrospinal fluid. The distribution of 5-HIAA levels was bimodal. Patients in the low 5-HIAA mode (below 15 ng/ml) attempted suicide significantly more often than those in the high mode, and they used more violent

5-HIAA in Cerebrospinal Fluid and Deficit Schizophrenic Characteristics
British Journal of Psychiatry, 1990Higher CSF 5-HIAA concentrations and lower CSF HVA concentrations have been associated with various measures of slowed motor behaviour and communication in schizophrenic patients. To derive a single, reliable measure of deficit characteristics in schizophrenic patients, we entered four items of the BPRS reflecting negative symptoms, a work history ...

Differential timing of amino acid and 5-HIAA rhythms in suprachiasmatic hypothalamus [PDF]
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1993 In vivo brain microdialysis was used to characterize the daily pattern of extracellular excitatory amino acids (EAA; glutamate and aspartate), glutamine and 5-hydroxyindoleacetic acid (5-HIAA) in the region of the suprachiasmatic nucleus (SCN) in freely behaving male Syrian hamsters.

5‐HIAA in Cerebrospinal Fluid of Patients with Status Epilepticus
Epilepsia, 1984Summary:Cerebrospinal fluid concentration of 5‐hydroxyindolacetic acid (5‐HIAA) was determined in 15 patients soon after recovery from status epilepticus. Similarly, patients with generalised epilepsy and persons without epilepsy, serving as controls, were also studied.

5-HT and 5-HIAA in cerebrospinal fluid in depression
Journal of Affective Disorders, 1987CSF 5-HT and 5-HIAA were measured in endogenously depressed patients (ICD-9) (n = 23) and controls (n = 11). Distribution of sex, age and body height was similar in the two groups. Non-parametric statistics were used. In depressed patients CSF 5-HT concentrations were found to be higher (P less than or equal to 0.01) than in controls.
