What type of overdose is indicated by altered mental status with pin-point pupils?

The indication of altered mental status combined with pin-point pupils is characteristic of a narcotic overdose. Narcotics, also known as opioids, can depress the central nervous system, leading to a decreased level of consciousness and other neurological symptoms, such as altered mental status. One of the hallmark signs of an opioid overdose is miosis, or constricted pupils, commonly described as "pin-point," which is distinctly associated with the influence of narcotics on the body's systems.

In contrast, stimulant overdoses, such as cocaine, typically result in symptoms like dilated pupils, increased heart rate, and heightened alertness rather than altered mental status with constricted pupils. Alcohol overdoses can cause confusion and other symptoms but do not typically result in pin-point pupils. Lastly, barbiturates can lead to sedation and respiratory depression, but again, they do not lead specifically to the miosis observed in narcotic overdoses. Thus, the combination of the described symptoms is diagnostic of narcotic overdose.
