Yes, personal injury can be mental. Mental injuries would come under “non-economic compensation.” Although no two cases are alike, they usually consist of economic and non-economic damages. Economic damages encompass the tangible costs you've incurred due to your injury, such as medical expenses, necessary treatments, therapy, doctor's visits, rehabilitation, prescription drugs, etc. Moreover, they may also include loss of income if you were unable to work after the injury, probable future earnings you could have earned if not for the accident, and other consequential costs.
