Background:
A defective emotional enhancement of verbal memory (VM) performances has been reported in different neurological diseases.
Objectives:
To assess the emotional enhancement of VM in 22 Clinically Isolated Syndrome (CIS) suggestive of Multiple Sclerosis (MS) and 49 Relapsing (RR) MS patients in comparison to 32 Healthy Controls (HC).
Methods:
Immediate and delayed recall of VM was assessed using the Selective Reminding Test (SRT). A list of 12 emotionally significant words was used to evaluate the Emotional (E) variants of the SRT. Depressive symptoms were assessed by the Beck Depression Inventory.
Results:
The prevalence of depression did not differ between RRMS and CIS patients. Both patient groups showed poorer (p<0.01) VM performances in comparison to HC in all the SRT tasks, but no difference was found between the two patient groups. Emotionally salient words were more (p<0.0001) recalled than neutral words in HC and CIS, but not in RRMS patients, while performing the immediate recall tasks. Delayed recall was not affected by emotional stimuli in both CIS and RR MS groups. The presence of depressive symptoms did not influence the VM performances.
Conclusions:
Our results demonstrate a defective emotional enhancement of VM in definite MS and, although to a lesser extent, in CIS patients.

Negative and Cognitive Symptoms of Schizophrenia
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Amnesia
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
Anterograde...
