Published: March 2013

Neurotensin (NT) is a tridecapeptide that is found in the central nervous system (CNS) and the gastrointestinal tract. NT behaves as a neurotransmitter in the brain and as a hormone in the gut. Additionally, NT acts as a neuromodulator to several neurotransmitter systems including dopaminergic, sertonergic, GABAergic, glutamatergic, and cholinergic systems. Due to its association with such a wide variety of neurotransmitters, NT has been implicated in the pathophysiology of several CNS disorders such as schizophrenia, drug abuse, Parkinson's disease (PD), pain, central control of blood pressure, eating disorders, as well as, cancer and inflammation. The present review will focus on the role that NT and its analogs play in schizophrenia, endocrine function, pain, psychostimulant abuse, and PD.

The purpose of this review was to analyse the literature regarding the correlation between the level of tryptamine, aryl hydrocarbon receptor (AHR) signalling pathway activation, and monoamine oxidase (MAO)-A and MAO-B activity in health and conditions such as neurodegenerative, neurodevelopmental, and psychiatric disorders. Tryptamine is generated through the decarboxylation of tryptophan by aromatic amino acid decarboxylase (AADC) in the central nervous system (CNS), peripheral nervous system (PNS), endocrine system, and gut bacteria. Organ-specific metabolism of tryptamine, which is mediated by different MAO isoforms, causes this trace amine to have different pharmacokinetics between the brain and periphery.

[Elements of high-grade iatrogenic risk in care of patients with somatic symptom disorder].

Psychiatr Hung

January 2025

Rosszullétek speciális elme- és ideggyógyászati szakrendelô, Budapest, Hungary, E-mail:

Author analyses the process of care of somatic symptom disorder in the general medical practice with special concern to iatrogenic harms. In his opinion the latency of the patients' first appointment with a psychiatrist or clinical psychologist is caused by multiple factors. Patients do not have knowledge on the basic activities of central nervous system necessary to recognize the pathomechanism.

Multiple sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system (CNS) that is usually diagnosed between the ages of 20 and 40. Changes in the immune system also observed in cancer may suggest a higher prevalence of cancer in the MS patient population. In recent years, many highly effective immunosuppressive drugs have been introduced into disease-modifying therapy (DMT) which may be associated with a higher risk of cancer development in patients with MS.

Multiple sclerosis (MS) is a chronic inflammatory disease affecting the central nervous system (CNS). There is a significant delay in diagnosing MS as the symptoms and tests overlap with other diseases. Blood-based biomarkers, which quantify fragments of proteins involved in MS pathophysiology, have the potential as diagnostic biomarkers.

Background: Narcolepsy, a central hypersomnolence disorder, disrupts sleep regulation. Sodium oxybate, a CNS (central nervous system) depressant, is widely used as a treatment, but there are surprisingly very few rigorous studies comparing its effectiveness to placebo in adults.

Objectives: To measure the comparative efficacy of sodium oxybate at a dosage regimen of 9 g versus placebo in improving nighttime sleep quality, reducing nocturnal arousals and sleep stage shifts, and enhancing the overall refreshed nature of sleep in adult patients with narcolepsy.
