Which racetam has the strongest evidence?
Racetams are a family of synthetic compounds built around a 2-pyrrolidone “racetam” core. The original member, piracetam, has been marketed for decades in parts of Europe and elsewhere for a grab-bag of neurological indications—while also becoming a staple of the modern “nootropics” scene. Newer analogues—aniracetam, oxiracetam, pramiracetam, nefiracetam, and others—were developed to tweak potency, pharmacokinetics,…
Keep readingThiamine Analogues: Benfotiamine vs. Sulbutiamine
Thiamine (vitamin B1) is best known for what happens when it’s missing: confusion, memory problems, and—in severe deficiency—Wernicke encephalopathy and Korsakoff syndrome. That clinical reality hints at why thiamine biology keeps resurfacing in “brain optimization” conversations. Neurons are unusually dependent on glucose metabolism, and several key enzymes in energy and neurotransmitter pathways require thiamine in…
Keep readingNicotine: Is It Really Neuroprotective?
Nicotine Class: Acetylcholine 6/10 Short-term cognitive boost 2/10 Long-term brain enhancement 4/10 Health and Safety Profile 6/10 Quality & strength of evidence Nicotine is best known as the addictive drug that sustains tobacco dependence. But because nicotine activates neuronal nicotinic acetylcholine receptors (nAChRs)—a widespread receptor family that modulates neurotransmission, plasticity, inflammation, and cell-survival signalling—researchers have…
Keep readingIs It Possible To Create New Dopamine Neurons?
Dopamine (DA) neurons—especially the midbrain DA neurons in the substantia nigra pars compacta (SNpc) and ventral tegmental area (VTA)—are central to movement, motivation, and reward, and their degeneration drives Parkinson’s disease (PD). If the adult brain could naturally replace these neurons, it would transform how we think about PD progression and treatment. The problem is…

In the United States, a national parent survey estimate suggests 7.0 million children aged 3–17 (11.4%) had ever been diagnosed with ADHD in 2022. Among children with current ADHD, about 53.6% were taking ADHD medication in 2022. Broader prescribing data also show sustained growth: a DEA-commissioned report found dispensed stimulant prescriptions increased by ~34% from…
Keep readingIs your ADHD medication safe?
Introduction ADHD medications are prescription treatments used to reduce the core symptoms of attention-deficit/hyperactivity disorder—inattention, hyperactivity, and impulsivity—so that day-to-day functioning (school, work, relationships, driving, organisation) is easier. They don’t “cure” ADHD, but for many people they meaningfully improve focus, self-control, and emotional regulation when used as part of a broader plan (skills, routines, coaching/therapy,…
Keep readingModafinil: A safe “smart-drug”?
Modafinil Class: Stimulant 7/10 Short-term cognitive boost 2/10 Long-term brain enhancement 6/10 Health and Safety Profile 7/10 Quality & strength of evidence Modafinil is a prescription wakefulness-promoting medication used to help people stay awake when a medical condition causes excessive daytime sleepiness. In the United States, modafinil (brand name Provigil, among others) is approved to…
Keep readingDo SSRIs improve neurogenesis?
Introduction Selective serotonin reuptake inhibitors (SSRIs) are among the most commonly prescribed antidepressant medications. Clinicians use them primarily to treat major depressive disorder, and they’re also widely prescribed for anxiety-related conditions such as panic disorder, social anxiety disorder, obsessive–compulsive disorder (OCD), and post-traumatic stress disorder (PTSD). Common SSRIs include sertraline, fluoxetine, citalopram, escitalopram, paroxetine, and…
Keep readingLithium: The Key To Neurogenesis?
Lithium has been a cornerstone treatment for bipolar disorder for more than half a century, praised for its ability to steady mood when life feels like it’s swinging wildly between extremes. Yet one question has stubbornly lingered: what is lithium actually doing inside the brain? An article published in Nature by Palmos et al. proposed…
