Atypical Alzheimer's dementia: Addressing the subtypes, epidemiology, atypical presentations, diagnostic biomarkers, and treatment updates.

Alzheimer's disease is a progressive neurodegenerative disorder that primarily affects the elderly population; and is characterized by the gradual loss of memory, cognition, and ability to carry out daily activities. However, a growing body of research indicates that there exists a subtype of Alzheimer's disease known as Atypical Alzheimer's disease. Atypical Alzheimer's disease is a rare form of dementia that differs from the typical presentation of Alzheimer's disease, such as variations in the age of onset, distribution of brain pathology, and clinical symptoms.

A case report of anti-NMDA receptor encephalitis in a 23-year-old female with acute psychiatric symptoms.

Key Clinical Message: Prompt identification and management of anti-N-methyl-D-aspartate receptor encephalitis in young patients with acute psychiatric symptoms, seizures, and neurological deficits are crucial. Timely immunomodulatory therapy is essential for positive outcomes and minimizing long-term complications. High suspicion for this rare disorder is necessary for timely diagnosis and optimal care.

Neurological, cardiac, musculoskeletal, and renal manifestations of scleroderma along with insights into its genetics, pathophysiology, diagnostic, and therapeutic updates.

Background: Scleroderma, also referred to as systemic sclerosis, is a multifaceted autoimmune condition characterized by abnormal fibrosis and impaired vascular function. Pathologically, it encompasses the persistent presence of inflammation, abnormal collagen buildup, and restructuring of blood vessels in various organs, resulting in a wide range of clinical symptoms. This review incorporates the most recent scientific literature on scleroderma, with a particular emphasis on its pathophysiology, clinical manifestations, diagnostic approaches, and treatment options.

Association of multiple sclerosis with stroke: A comprehensive review.

Background: Multiple sclerosis (MS) is a chronic immune-mediated disorder characterized by the degradation of the myelin sheath in the central nervous system. Research indicates that individuals with MS exhibit a higher susceptibility to stroke compared to the general population. This association is rooted in shared underlying mechanisms, specifically involving neuroinflammatory processes.

Adult-onset acute disseminated encephalomyelitis: a rare case report in a 26-year-old female and review of literature.

Acute disseminated encephalomyelitis is a demyelinating autoimmune condition that mostly affects the central nervous system. We present a case of a woman who presented with paralysis and speech deficits following an episode of upper respiratory tract infection. Brain and spinal cord imaging were used to confirm the diagnosis.

Remyelination in multiple sclerosis, along with its immunology and association with gut dysbiosis, lifestyle, and environmental factors.

Multiple sclerosis (MS) is a chronic inflammatory disease that damages the myelin sheath around the axons of the central nervous system. While there are periods of inflammation and remyelination in MS, the latter can sometimes be insufficient and lead to the formation of lesions in the brain and spinal cord. Environmental factors such as vitamin D deficiency, viral or bacterial infections, tobacco smoking, and anxiety have been shown to play a role in the development of MS.

Comparison of recent updates in genetics, immunology, biomarkers, and neuroimaging of primary-progressive and relapsing-remitting multiple sclerosis and the role of ocrelizumab in the management of their refractory cases.

Background: Primary-progressive multiple sclerosis (PPMS) and relapsing-remitting multiple sclerosis (RRMS) are two frequent multiple sclerosis (MS) subtypes that involve 10%-15% of patients. PPMS progresses slowly and is diagnosed later in life. Both subtypes are influenced by genetic and environmental factors such as smoking, obesity, and vitamin D insufficiency.

Ulcerative colitis: Addressing the manifestations, the role of fecal microbiota transplantation as a novel treatment option and other therapeutic updates.

The prevalence and incidence of Ulcerative Colitis (UC), a recurrent and remitting inflammatory condition, are rising. Any part of the colon may be affected, beginning with inflammation of the mucosa in the rectum and continuing proximally continuously. Bloody diarrhea, tenesmus, fecal urgency, and stomach pain are typical presenting symptoms.
