Studies show that increasing the amount of tyrosine and phenylalanine in the diet can increase dopamine levels in the brain, which may promote deep thinking and improve memory ( 7 , 9 , 10 ).

What happens when you block dopamine receptors?

Dopamine receptor blocking agents are known to induce parkinsonism, dystonia, tics, tremor, oculogyric movements, orolingual and other dyskinesias, and akathisia from infancy through the teenage years. Symptoms may occur at any time after treatment onset.
