We can understand your distress related to these biological phenomenon
Do not worry, in mood disorders such as depression, anxiety or disturbed sleep, there is no such permanent damage to brain tissue, their etiology is different
For example, In most of the mood disorders or Psychiatric illness, there is imbalance of neurotransmitter as serotonin, dopamine, cortisol etc, this variation does not damage neurons , these neurotransmitters work at respective receptors
Medications for these mood disorders work at receptor level by normalisation of these neurotransmitters that are called chemicals in general term
In dementia , there is damage to neurons, or other brain organic conditions such as tumour, epilepsy etc,there is damage to neurons
