Multiple sclerosis (MS) patients showed no differences in memory span or learning curves but did exhibit deficits in word recall order. This suggests specific acquisition-retrieval issues in MS impacting serial position memory.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Clinical Neurology

Background:

  • Multiple sclerosis (MS) is a demyelinating disease affecting the central nervous system.
  • Cognitive impairments, particularly in memory, are common in MS patients.
  • Understanding acquisition-retrieval deficits is crucial for managing MS-related cognitive decline.

Purpose of the Study:

  • To investigate acquisition-retrieval deficits in Spanish-speaking patients with multiple sclerosis.
  • To compare memory performance between MS patients and a healthy control group using the Rey Auditory-Verbal Learning Test (RAVLT).

Main Methods:

  • Utilized the Spanish version of the Rey Auditory-Verbal Learning Test (RAVLT).
  • Administered the RAVLT to a group of 10 MS patients and 10 healthy controls.

  • Analyzed memory span, learning curve, and serial position curve data.
  • Main Results:

    • No significant differences were observed between MS patients and controls in memory span or learning curve.
    • Significant differences were found in the serial position curve, indicating impaired recall order in MS patients.
    • The recency effect was absent in the immediate recall condition for the MS group.

    Conclusions:

    • MS patients exhibit specific deficits in the retrieval of information based on its order, as evidenced by the serial position curve.
    • The absence of a recency effect suggests difficulties in recalling recently presented items.
    • Findings contribute to understanding the pattern of cognitive impairment in multiple sclerosis.
