New research reveals that people with a history of methamphetamine dependence face a startling elevated risk of developing Parkinson’s disease or related movement disorders later in life. Key Facts: Individuals dependent on methamphetamine had almost 3 times the rate of Parkinson’s outcomes compared to matched controls from the general population. For women with methamphetamine dependence, the risk …
A new Mayo Clinic study is the first to clinically investigate whether antidepressants that impact mitochondrial function differently are associated with varying rates of treatment-emergent mania in bipolar disorder. The study found that antidepressants that increase mitochondrial energetics were associated with nearly double the rates of treatment-emergent mania compared to antidepressants that decrease mitochondrial energetics. …
Stimulants like caffeine, methylphenidate, and modafinil have repeatedly been shown to boost cognitive abilities such as attention, focus, and memory in healthy individuals. A new study provides insight into the underlying brain mechanisms of this cognitive enhancement effect. Key Facts: All three stimulants (caffeine, methylphenidate, modafinil) enhanced performance across different memory tasks Stimulants increased functional …
A large review of research found that talk therapy works about as well as antidepressant medications for treating depression. The study also looked at other non-drug options, like exercise. While benefits were similar across treatments, side effects differed. Key Facts: Cognitive behavioral therapy (CBT) achieved comparable results to medications for treating major depression. Remission rates …
Anti-cancer peptides (ACPs) offer a potentially more targeted way to detect and treat cancer compared to conventional therapies like chemotherapy. ACPs can discriminate between cancerous and healthy cells, resulting in fewer side effects. Key Facts: ACPs can actively penetrate and kill tumor cells or enhance the immune system’s response against tumors They have high specificity, …
The naturally occurring peptide BPC 157 shows potential to treat stroke, schizophrenia symptoms, and spinal cord injury in animal models. Key facts: BPC 157 rapidly counteracted stroke damage and led to full recovery of memory, coordination and movement in rats. The peptide alleviated schizophrenia-like symptoms and catalepsy in rodent models by modulating dopamine, glutamate and …
Researchers uncover a surprising molecular mechanism that explains ketamine’s exceptionally long-lasting antidepressant effects. Key Facts: Ketamine’s antidepressant effects last for days after its concentration drops to low, ineffective levels only an hour after administration. This contrasts starkly with ketamine’s short 13-minute half-life in the body. Ketamine continues blocking NMDA receptors and suppressing activity in the …
Researchers have discovered that several commonly prescribed antidepressants can promote antibiotic resistance and persistence in E. coli bacteria. This concerning finding implicates yet another widely used class of pharmaceuticals in exacerbating the global antibiotic resistance crisis. Key Facts: Antidepressants including sertraline and duloxetine were found to significantly increase E. coli’s resistance to multiple antibiotics like …
Researchers conducted a comprehensive analysis comparing 20 antidepressants to identify the most effective options for preventing relapse in patients with major depressive disorder (MDD). Their findings suggest desvenlafaxine, paroxetine, venlafaxine and vortioxetine balance efficacy and tolerability best for maintenance treatment. Key Facts: The analysis included 34 high-quality clinical trials with over 9,300 patients total. All …
Researchers explore various drug compounds and their potential to enhance human cognition, including attention, learning, and higher-order thinking. While some progress has been made, many questions remain. Key Facts: Several drug compounds show potential to mildly enhance some cognitive functions like attention, learning, and memory. These include stimulants, wakefulness agents, and compounds that affect memory …
