Ф Some reports – it is inherited disorder
but many other don’t agree
Ф Serious societal problem
PPRC/INDIA 12
Pathogenesis
Monoamine theory
PPRC/INDIA 13
Ф Monoamines like noradrenalin,
dopamine, serotonin work as
stimulating neurotransmitters in the
brain
PPRC/INDIA 14
Ф The amount of monoamines deplete in
the pre-synaptic neurons is decreased &
also in synaptic spaces
Ф Thus neurotransmission is diminished
Ф Life activity is decreased - depression
PPRC/INDIA 15
Symptoms
PPRC/INDIA 16
Ф Decrease in appetite
Ф Low activity
Ф Hesitate to meet
Ф Don’t feel like working
Ф No interest in societal activity
PPRC/INDIA 17
Present drugs for depression
PPRC/INDIA 18
Ф Imipramine
Ф Monoamine oxidase inhibitors
Ф Modified tricyclic acids / tetracyclic
acids
PPRC/INDIA 19
Ф Selective serotonin receptor inhibitors
Ф Serotonin – noradrenalin receptor
inhibitors
PPRC/INDIA 20
Research findings
PPRC/INDIA 21
Ф Hippocampus is reduced in patients
Ф It is restored as the patient recovers
Ф Drugs promote regeneration /
degeneration
PPRC/INDIA 22
Ф Brain-derived neurotrophic factor
(BDNF) plays important role
Ф Increase BDNF in the hippocampus
decrease causes depression
PPRC/INDIA 23
Ф Disruption of neurogenesis completely
abolished with drug
Ф Inducer of neurodegenerative in
depression is not clear
Ф Glucocorticoid cause depression in
animals
PPRC/INDIA 24
Choice of others to treat
PPRC/INDIA 25
Ф Herbal medicines
Ф Electroconvulsive theory
Ф Sleep deprivation method
PPRC/INDIA 26
Ф Psychological approach
Ф Yoga & meditation approach
Ф Religious method
PPRC/INDIA 27
Opportunities

Ф Misc. approach methods
Ф Mechanism
Ф Study of Eugenol in Alzheimer’s &
Parkinson’s diseases
