Delirium is a challenging medical problem, particularly in the home care setting, and greatly affects both patients and family caregivers. When delirium is not immediately detected and effectively managed, various outcomes are adversely affected. This report describes delirium in an older home-bound man and offers strategies for detecting and managing delirium in a home care setting. The patient is a frail 86-year-old man with multiple medical comorbidities and functional decline after bronchitis that was diagnosed by a general practitioner. Following the diagnosis and subsequent treatment of bronchitis, the patient suffered a major decline in cognitive and physical functioning during normal daily activities. Medical screening revealed confusion, apathy, and extreme fatigue. Using the assessment tool of the Functional Independence Measures and Delirium Observation Screening Scale (DOSS), the presence of functional decline and delirious symptoms were found. Through multidisciplinary collaboration, a treatment plan was initiated. It consisted of hydration following a fixed schedule, adapted nutrition, a temporary adapted medication schedule for pre-diabetes, and an exercise plan. No specific pharmaceuticals were given. The patient made a full recovery over time. All professional and informal caregivers should be aware of the potential presence of delirium when an older patient with a deteriorating physical or mental condition presents itself. Good diagnostics for delirium and possible underlying diseases are necessary. Adequate treatment, with the help of paramedics such as dieticians, physiotherapists, etc. must be provided when necessary.

Urinary tract infection (UTI) is common in older adults, mainly due to several age-related risk factors. Symptoms of UTI are atypical in the elderly population, like hypotension, tachycardia, urinary incontinence, poor appetite, drowsiness, frequent falls, and delirium. UTI manifests more commonly and specifically for this age group as delirium or confusion in the absence of a fever. This systematic review aims to highlight the relationship between UTI and delirium in the elderly population by understanding the pathologies individually and collectively. A systematic review is conducted by searching PubMed with regular keywords and major Medical Subject Heading (MeSH) keywords, Science Direct, and Google Scholar. The inclusion criteria consisted of studies based on male and female human populations above the age of 65 in the English language, available in full text published between 2017 and 2022. However, the exclusion criteria were animal studies, clinical trials, literature published before 2017, and papers published in any other language except English. A total of 106 articles were identified, and nine final studies were selected after a quality assessment, following which a valid relationship between delirium and UTI was identified in this systematic review.

Moyamoya disease (MMD) is a rare, progressive cerebrovascular disorder that occurs when the major arteries supplying the brain become narrowed or obstructed. Because of this, small and delicate collateral vessels develop to compensate for the decrease in blood flow. Unfortunately, these vessels are insufficient to meet the brain\'s metabolic demands. Though initially described in Japan, MMD occurs in a variety of ethnicities around the world. The clinical manifestations of the disease can be devastating, with patients often presenting with symptoms of a stroke or transient ischemic attack. The long history of insults and chronic changes to the brain makes these individuals susceptible to alterations in their mental status. We describe a case of a young African American female with a history of sickle cell anemia (SCA) and undiagnosed MMD who presented to the emergency department with community-acquired pneumonia (CAP). In addition to her medical derangements, she also presented with paranoia, delusional guilt, and refusal to speak.
