11. Absence of Lasting Impact: TGA’s Non-Progressive Nature
TGA is a non-progressive condition. In the landscape of neurological disorders, many diseases like Alzheimer’s or Parkinson’s disease are progressive, meaning they worsen over time. However, TGA stands apart in this regard.
Once a TGA episode ends, the individual’s cognitive functions return to normal. There is no lasting cognitive impairment or degradation of mental functions over time. The person can resume their daily activities as if the episode never occurred.
This return to normalcy also extends to the individual’s memory. All memories before the episode remain intact, and the ability to form new memories resumes. There’s a distinct ‘cut-off’ point, after which memory formation returns to normal.
The non-progressive nature of TGA makes it a unique anomaly among memory disorders. This characteristic has significant implications for treatment and management, as no long-term cognitive interventions are necessary. (11)
