✿ Root Causes
Root Causes & Triggers
Chemical Imbalances
Alterations in brain chemistry, particularly concerning serotonin, norepinephrine, and dopamine pathways.
Hormonal Changes
Shifts in hormones, such as those related to the thyroid, menstruation, pregnancy, or postpartum phases.
Trauma and Grief
Unresolved trauma, loss of a loved one, or significant life changes that overwhelm emotional coping mechanisms.
Islamic Perspective
"Those who succumb to depression and refuse to fight it are weak and failures in life, whereas those who patiently resist negative thoughts and face problems with renewed optimism are strong and successful. The depressed person should ask himself which of the two groups he would want to identify with."
Reflection & Clinical Context
In his groundbreaking manuscript 'Masalih al-Abdan wa al-Anfus' (Sustenance of the Soul), Al-Balkhi became the first to distinguish between neurogenic and psychogenic depression. He pioneered early cognitive behavioral therapy (CBT) by teaching patients to actively challenge depressive internal thoughts rather than passively accepting them.
