ICD-10: F19.16

ICD-10 code F19.16 refers to "Other psychoactive substance abuse with psychoactive substance-induced persisting amnestic disorder." This classification falls under the broader category of psychoactive substance-related disorders, which are characterized by the harmful use of substances that affect mental functioning and behavior.

Clinical Description

Definition

F19.16 specifically denotes a condition where an individual exhibits a pattern of abuse of psychoactive substances that leads to a persisting amnestic disorder. This disorder is characterized by significant memory impairment that persists beyond the immediate effects of the substance use. The amnestic disorder is primarily caused by the toxic effects of the substance, which can disrupt normal cognitive functioning and memory processes.

Symptoms

Individuals diagnosed with F19.16 may experience a range of symptoms, including:

• Memory Loss: Difficulty recalling recent events or forming new memories, which can be profound and persistent.
• Confusion: Disorientation regarding time, place, or identity.
• Impaired Learning: Challenges in acquiring new information or skills.
