We describe the case of a 59-year-old woman who exhibited psychotic symptoms, cognitive dysfunction, and restlessness. While the clinical picture and 18F-FDG PET/CT suggested the presence of a tauopathy, especially frontotemporal dementia or progressive supranuclear palsy, genetic testing eventually revealed Huntington's disease.

Introduction: Neuroinflammation is correlated to neurodegenerative diseases like Alzheimer's disease (AD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), Huntington Disease (HD) and Parkinson's disease (PD). A lot of recent research and patents are focused on the design and synthesis of arachidonic acid Lipoxygenase (ALOX) inhibitors for the treatment of neurodegenerative diseases.
Areas Covered: The survey covers natural products, synthesis, hybrids, and assessments of biological effects in biological studies as ALOX inhibitors.

Background: Altered balance between striatal direct and indirect pathways contributes to early motor, cognitive and psychiatric symptoms in Huntington disease (HD). While degeneration of striatal D2-type dopamine receptor (D2)-expressing indirect pathway medium spiny neurons (iMSNs) occurs prior to that of D1-type dopamine receptor (D1)-expressing direct pathway neurons, altered corticostriatal synaptic function precedes degeneration. D2-mediated signaling on iMSNs reduces their excitability and promotes endocannabinoid (eCB) synthesis, suppressing glutamate release from cortical afferents.

Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder traditionally characterized by the selective loss of medium spiny neurons in the basal ganglia. However, it has become apparent that white matter injury and oligodendrocyte dysfunction precede the degeneration of medium spiny neurons, garnering interest as a key pathogenic mechanism of HD. Oligodendrocytes are glial cells found within the central nervous system involved in the production of myelin and the myelination of axons.

Huntington's disease is an inherited neurodegenerative disorder caused by a CAG repeat expansion that encodes a polyglutamine tract in the huntingtin (HTT) protein. The mutant CAG repeat is unstable and expands in specific brain cells and peripheral tissues throughout life. Genes involved in the DNA mismatch repair pathways, known to act on expansion, have been identified as genetic modifiers; therefore, it is the rate of somatic CAG repeat expansion that drives the age of onset and rate of disease progression.

Prosthetic joint infection (PJI), caused by Streptococcus bovis group (SBG), is uncommon and related to colorectal cancer. We present here a case of an 84-year-old male who had a past medical history of chronic obstructive pulmonary disease (COPD), congestive heart failure, pulmonary arterial hypertension, iron deficiency anemia, chronic kidney disease, diabetes mellitus, gout, hypertension, bilateral knee replacement with left knee pain and swelling. We initially suspected gout and treated him with prednisolone, but it did not relieve him.
