Chronic Kidney Disease II: Clinical Manifestations

520
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Coronary Artery Disease III: Clinical Manifestations

299
Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

364
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Heart Failure III: Clinical Manifestations

436
Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

Hypertension III: Clinical Manifestations and Diagnostic Studies01:30

Hypertension III: Clinical Manifestations and Diagnostic Studies

437
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

科学分野:

  • 神経科学
  • 神経学
  • 老年学

背景:

  • 行動変異型前頭側頭型認知症（bvFTD）は、性比の不均衡と、孤発性および遺伝性症例間、特に女性における異なる症状を示す。
  • 遺伝子変異を持たない女性は、非定型的なbvFTD症状の提示により、アルツハイマー病（AD）と誤診される可能性がある。

研究 の 目的:

  • アルツハイマー病（AD）の臨床的および認知的提示における性差を調査すること。
  • 非定型的なbvFTD様症状を持つ女性のADとしての診断上の誤分類の可能性を探ること。

主な方法:

  • 性別層別化された神経精神症状（NPI-Q）および認知機能の評価を含む、国立アルツハイマー病調整センター（NACC）データセット（N=11,286）の分析。
  • 年齢、疾患重症度、教育歴を補正した若年発症AD（年齢<65歳）および晩発性ADのサブグループ分析。

主要な成果:

  • 女性は男性と比較して、より重度の実行機能障害とうつ病を示した。
  • 男性は、より重度の易怒性、無関心、脱抑制、興奮、および夜間の行動障害を示した。
  • 若年発症ADの男性は、より重度の運動障害、脱抑制、および妄想を示した。

結論:

  • 認知および行動的側面を含む、AD症状の提示における有意な性関連の違いが特定された。
  • これらの性特異的な違いは、特にbvFTD様症状を持つ女性をADと誤診する可能性があり、診断上の課題をもたらす可能性がある。
  • ADにおける診断精度の向上と患者管理のためには、性別に基づく症状の変動性の認識を高めることが不可欠である。
