Read the passage below and answer the questions as instructed:-

Driving back home Shriya experienced increased heart beat, shortness of breath, dizziness, trembling, palpitations and she started having a feeling of discomfort. She was so scared that she stopped the car and sat on the pavement. In the next few months, frequency of these attacks increased, and the fear of being caught in the traffic was so high that she stopped driving. She felt that she was going crazy and losing control on herself.

Which neurotransmitter is responsible for the disorder highlighted in the case study?

Low activity of GABA

The symptoms described in the case study, such as increased heart rate, shortness of breath, dizziness, trembling, palpitations, and feelings of discomfort, are indicative of a panic or anxiety disorder.

Anxiety disorders have been linked to low activity of the neurotransmitter gamma aminobutyric acid (GABA).

Schizophrenia is due to excess activity of dopamine, and depression to low activity of serotonin.
