Recent studies have shown that alcohol use affects the regulation and expression of proprotein convertase subtilisin/kexin 9 (PCSK9). While a major role of PCSK9 in hepatic function and lipid regulation has been clearly established, other pleiotropic effects remain poorly understood. Existing research suggests a positive association between PCSK9 expression in the brain and psychopathology, with increased levels of PCSK9 in the cerebrospinal fluid (CSF) of individuals with dementia and epigenetic modifications of PCSK9 associated with Alcohol Use Disorder (AUD). In this study, we hypothesized that chronic alcohol use would increase PCSK9 expression in CSF.

Interoception may contribute to substance use disorder as it relates to the body's experience of substance use or withdrawal. However, only a few studies have directly investigated associations betwee...

Alcohol use disorder is a major societal and individual burden that exacerbates health outcomes, decreases quality of life, and negatively affects U.S. healthcare spending. Although pharmacological tr...
Proton Magnetic Resonance Spectroscopy ( H-MRS) studies have demonstrated abnormal levels of a variety of neurometabolites in inpatients/outpatients with Alcohol Use Disorder (AUD) following acute alc...
Treatment-seeking men with alcohol use disorder (AUD) classically exhibit a blunted hypothalamic-pituitary-adrenal (HPA) axis response to pharmacologic and behavioral provocations during the early pha...
A small percentage of individuals with alcohol use disorder (AUD) obtain alcohol-related care despite research showing that treatment is effective. This randomized controlled trial tests t...
This research will be achieved by the assessment of p75NTR-ECD expression (total and linked to different species of Aβ (Aβ1-40 and Aβ-1-42)) within the cerebrospinal fluid (CSF) of pati...
This study will examine the efficacy of the medication gemfibrozil in reducing alcohol consumption in individuals with an alcohol use disorder who are seeking treatment for alcohol-related...
The primary goal is to quantify cerebrospinal fluid (CSF) volume, diffusion characteristics and mechanical properties of brain tissue at two states of arousal.
Cerebrospinal fluid is a clear, colorless fluid that circulates in the cranial and spinal subarachnoid spaces, located between the pia and arachnoid matters. It is mainly produced by the c...
Discharge of cerebrospinal fluid through a hole through the skull bone most commonly draining from the nose (CEREBROSPINAL FLUID RHINORRHEA) or the ear (CEREBROSPINAL FLUID OTORRHEA).
Tubes inserted to create communication between a cerebral ventricle and the internal jugular vein. Their emplacement permits draining of cerebrospinal fluid for relief of hydrocephalus or other condition leading to fluid accumulation in the ventricles.
An intermittent and self-limiting headache disorder in individuals with CEREBROSPINAL FLUID SHUNTS emplaced for the treatment of HYDROCEPHALUS. The symptoms of headache, vomiting, and cranial neuropathies are associated with intermittent obstruction of the shunt.
Discharge of cerebrospinal fluid through the nose. Common etiologies include trauma, neoplasms, and prior surgery, although the condition may occur spontaneously. (Otolaryngol Head Neck Surg 1997 Apr;116(4):442-9)
