MDMA is known for which of the following effects?

MDMA, also known as 3,4-methylenedioxymethamphetamine, primarily affects mood and perception, commonly associated with feelings of euphoria, empathy, and enhanced sensory perception. One significant concern with MDMA use is its potential to cause neurotoxic effects, particularly in high doses or when the drug is adulterated. This includes the risk of seizures, which can arise from factors such as overheating (hyperthermia), electrolyte imbalances, and increased serotonin release.

While MDMA does not typically lead to persistent dissociation from reality or frequent sedation, it is crucial to recognize that its stimulant properties may contribute to increased heart rate and energy, which is contrary to sedation. Additionally, the potential for dangerous effects like dehydration and overheating can impact a user's health and safety.

When considering overdose potential, MDMA does come with risks, particularly if taken in high quantities or mixed with other substances. Thus, it is important to be aware that the drug can indeed have a high risk of seizures under certain conditions, making this a prominent concern among its effects.
