Alpha and Theta Band Power Alterations on EEG are Linked to Psychological, but not Somatic, Symptom Severity in Patients with Major Depressive Disorder
(Al-Quds University, Deanship of Scientific Research, 2022-05-11) Nawras A. Sawafta; Abdul-Rahman S. Sawalma; Mohammad M. Herzallah
Background: Major depressive disorder (MDD) is a serious psychiatric disorder characterized by low mood, loss of pleasure, and other psychological and somatic symptoms. Previous studies show that MDD is associated with changes in alpha and theta oscillations measured by electroencephalography (EEG). Yet, most studies did not differentiate between subsets of MDD symptoms and their relationship to different brain oscillations.
Symptom Variability in Medication-Naïve Patients with Major Depressive Disorder as a Proxy to Predict Response to Treatment
(Al-Quds University, Deanship of Scientific Research, 2022-05-11) Rosaline Abu Sabbah; Abdul-Rahman S. Sawalma; Mohmmad M. Herzallah
Background: Major Depressive Disorder (MDD) is characterized by episodes of low mood and loss of interest for two or more consecutive weeks. It is considered to be the leading cause of morbidity and mortality worldwide. Only 30% of patients with MDD achieve full remission after treatment with antidepressants, psychotherapy or neuromodulation. It is unknown whether response to treatment depends on the baseline expression of MDD symptoms among patients.
