The major events of cardiac development, including early heart formation, chamber morphogenesis and septation, and conduction system and coronary artery development, are briefly reviewed together with a short introduction to the animal species commonly used to study heart development and model congenital heart defects (CHDs).

Background: Agitation is a common and disabling symptom of Alzheimer's dementia (AD). Pharmacological treatments are recommended if agitation is not responsive to psychosocial intervention. Citalopram was effective in treating agitation in AD but was associated with cognitive and cardiac risks linked to its R- but not S-enantiomer.

Background: The effect of high consumption of psychoactive substances of codeine (CDE), tramadol (TMD), and Cannabis sativa (CNB) as concoction has been associated with altered brain cognitive and neurochemical functions. However, the understanding of the complex mechanism behind the intake of Cannabis sativa co-administration with tramadol and codeine on both cardiac and brain function, neurotransmitters, purinergic, and antioxidant enzymes activities in the brain and heart of rats remains unreported.
Method: The measure of cognition using morris water maze (MWM) and Y-maze tests, hemodynamic parameters namely systolic blood pressure (SBP) and heart rate (HR), acetylcholinesterase (AChE), butyl-cholinesterase (BCHE), adenosine deaminase (ADA), arginase, catalase (CAT), superoxide dismutase (SOD) enzymes' activities, reduced glutathione (GSH) and malondialdehyde (MDA), nitric oxide (NO) levels, in the brain and heart of CNB, TMD, and CDE exposed rats was done.
Background: The new anti-Aβ antibody drugs aducanumab and lecanemab (approved in the US, not yet in Europe) must be followed up closely and regularly long-term. Previous knowledge on progression of AD in routine clinical settings longterm is crucial when introducing new dementia medications. The Swedish national quality database on dementia/cognitive disorders, SveDem, where data on different dementia disorders at the time of the dementia diagnosis since 2007 and on mild cognitive impairment (MCI) since 2021 with annual follow-ups of MMSE scores can provide this unique information.

Women account for almost two-thirds of Alzheimer's disease (AD) cases, yet evidence significantly less clinical benefit from recently deployed amyloid-lowering therapies. To close this disparity gap, there is an urgent need to identify biological drivers of sex differences in the manifestation and clinical response to AD therapeutics. A recent review of multi-omic studies of AD reported >75% of studies showed female-specific changes at the molecular level (vs.

Background: Aerobic exercise may positively affect brain health, although relationships with cognitive change are mixed. This likely is due to individual differences in the systemic physiological response to exercise. However, the acute effects of exercise on brain metabolism and biomarker responses are not well characterized in older adults or cognitively impaired individuals.
