Consider the following statements regarding Transient Global Amnesia (TGA): 1. TGA mainly affects middle aged persons who present with abrupt, discrete loss of anterograde memory lasting for few hours. 2. During the episode, the patients are unable to record new memories resulting in repetitive questioning. 3. Consciousness is impaired during the episode and the patient is unable to perform even simple motor functions. 4. After 4-6 hours, memory function and behaviour return to normal but the patient has complete and persistent amnesia for the duration of the episode. Which of the statements given above are correct?
To determine which statements about Transient Global Amnesia (TGA) are correct, let's analyze each one:
Statement 1: TGA mainly affects middle-aged persons who present with abrupt, discrete loss of anterograde memory lasting for a few hours.
This statement is correct. Transient Global Amnesia typically occurs in middle-aged or older adults and is characterized by a sudden onset of memory loss, particularly affecting the ability to create new memories (anterograde amnesia). This episode usually lasts several hours.
Statement 2: During the episode, the patients are unable to record new memories resulting in repetitive questioning.
This statement is correct. During a TGA episode, individuals cannot form new memories, leading them to repeatedly ask the same questions because they cannot remember recent answers.
Statement 3: Consciousness is impaired during the episode and the patient is unable to perform even simple motor functions.
This statement is incorrect. In TGA, while memory is affected, consciousness remains intact. Patients can perform motor tasks and are aware of themselves and their surroundings; they simply cannot retain new information.
Statement 4: After 4-6 hours, memory function and behavior return to normal but the patient has complete and persistent amnesia for the duration of the episode.
This statement is correct. After the TGA episode, memory and cognitive functions typically return to normal, although the person often has a permanent gap in memory for the period during the episode.
Given the above analysis, the correct statements regarding TGA are 1, 2, and 4. Thus, the correct option is:
1, 2 and 4
