Affecting millions worldwide, lysosomal storage disorders are rare genetic conditions caused by the accumulation of metabolic substrates within cells. The oral medication miglustat was developed to treat these conditions by tackling the root cause of the buildup, offering a versatile therapeutic approach.

At therapeutic doses, ivermectin does not readily cross the blood-brain barrier in humans, largely preventing significant central nervous system effects. However, in cases of overdose, specific genetic predispositions, or impaired barrier function, the drug can cause serious neurological problems by affecting the human brain.

Bacterial meningitis is a life-threatening medical emergency requiring immediate and effective antibiotic treatment. Given its widespread use for other infections, a common question is, **can amoxicillin treat meningitis?** The answer is complex: while generally unsuitable as a first-line therapy, it is crucial for combating specific bacterial types.

Synthetic oxytocin has a remarkably short half-life in the blood, typically around 3 to 6 minutes [1.4.3, 1.8.2]. This rapid clearance is central to understanding how is oxytocin absorbed in the body and why continuous administration is often necessary for clinical effects.

Every minute of an untreated stroke can result in the loss of nearly 2 million brain cells, a sobering statistic that underpins the critical urgency of treatment. For patients with an ischemic stroke, the clot-busting drug tissue plasminogen activator (tPA) is a primary treatment, but it is strictly governed by a time limit. This critical deadline is a pharmacological balancing act between restoring blood flow and avoiding a potentially catastrophic complication.

Over half of all stroke patients who receive tPA still experience some level of disability, but for many with an acute ischemic stroke, this medication is a game-changer. However, its use is strictly limited to a narrow time frame. The question of why you can't give tPA after 4.5 hours is rooted in a critical balance between therapeutic efficacy and the escalating risk of catastrophic complications.

Approximately one-third of individuals with epilepsy will develop drug-resistant epilepsy, a complex condition where seizures continue despite appropriate medication trials. Understanding **what causes drug-resistant epilepsy** is a major focus of neuroscience, with research identifying several biological and pharmacological factors at play.

Gamma-aminobutyric acid (GABA) is the human brain's primary inhibitory neurotransmitter, responsible for producing a calming effect [1.7.2, 1.2.1]. The key question for many is, **how long does it take for GABA to get into your system** after taking a supplement?

A 2006 study found that participants taking a GABA supplement reported feelings of relaxation within one hour. But **does GABA work immediately** for everyone, and what does the science say about its speed and effectiveness? This question is complex due to the blood-brain barrier and individual metabolic differences,.

An estimated one-third of US adults use a central nervous system (CNS)-active medication for various conditions, highlighting their widespread use in modern medicine. So, **what does CNS active mean** for these patients and others, and how do these powerful drugs influence our brain and body?
