Anticholinergics are used to treat various conditions, including Parkinson’s disease and urinary disorders. They work by blocking acetylcholine, a key neurotransmitter for memory and learning. Estudos mostram que aumentam o risco de demência. Por exemplo, um estudo da Universidade de Washington seguiu mais de 3,500 adultos mais velhos por 10 anos e encontrou que aqueles que regularmente usavam anticholinérgicas tinham um aumento de 54% de risco de demência em desenvolvimento.
Common anticholinergics linked to cognitive decline include meclizine, scopolamine, biperiden, oxybutynin, and diphenhydramine. However, others such as glycopyrronium and tiotropium have not shown these effects. Patients and physicians should carefully weigh the risks and benefits of these medications.
Corticosteroids and the Brain
Os corticosteroides são utilizados para tratar várias inflamações e doenças autoimunes. However, prolonged use, especially oral use, can cause serious side effects such as disorientation, anxiety, and depression. A British study found that people taking corticosteroids long-term had a higher risk of developing dementia.
Glucocorticoids like prednisone affect brain function by altering levels of the stress hormone cortisol. Even inhaled corticosteroids like fluticasone can have negative effects if used in high doses or for a long time. It is essential that healthcare professionals closely monitor their use and consider alternative treatments.
