OBJECTIVE Neuropeptide Y is a pancreatic polypeptide closely associated with noradrenergic activity both in the central and peripheral nervous systems. The objective of this study was to assess plasma neuropeptide Y-like immunoreactivity in panic disorder. METHODS Radioimmunoassays were performed in 12 patients with DSM-III-R panic disorder and two groups of normal comparison subjects (N = 22 and N = 16). RESULTS Markedly higher plasma neuropeptide Y-like immunoreactivity was found in patients with panic disorder. CONCLUSIONS Higher plasma neuropeptide Y-like immunoreactivity suggests that this peptide may be implicated in the etiology or expression of symptoms of panic disorder.

D008297 Male Males
D009478 Neuropeptide Y A 36-amino acid peptide present in many organs and in many sympathetic noradrenergic neurons. It has vasoconstrictor and natriuretic activity and regulates local blood flow, glandular secretion, and smooth muscle activity. The peptide also stimulates feeding and drinking behavior and influences secretion of pituitary hormones.

D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.

D016584 Panic Disorder A type of anxiety disorder characterized by unexpected panic attacks that last minutes or, rarely, hours. Panic attacks begin with intense apprehension, fear or terror and, often, a feeling of impending doom. Symptoms experienced during a panic attack include dyspnea or sensations of being smothered; dizziness, loss of balance or faintness; choking sensations; palpitations or accelerated heart rate; shakiness; sweating; nausea or other form of abdominal distress; depersonalization or derealization; paresthesias; hot flashes or chills; chest discomfort or pain; fear of dying and fear of not being in control of oneself or going crazy. Agoraphobia may also develop. Similar to other anxiety disorders, it may be inherited as an autosomal dominant trait.
