Hi @chloroform

found that the concentration of an enzyme called tyrosine hydroxylase which is essential in the production of dopamine in an HIV-positive patient was low. This will reduce the amount of dopamine produce which would affect patients in a different way depending on which side of the brain which is affected; if it affects the nigrostriatal pathway, patients will show some symptoms resembling Parkinson's disease and if it affects the mesolimbic pathway, clinical depression can be expected°...

This is to say the earlier the person is treated the better. Thank for letting us know that early treatment is important and it's a bad idea to not treat such disease.
