Compensation for material damage due to unlawful prosecution

I read about a case where a person was awarded compensation from the state only for moral damages due to many years of unlawful prosecution, while the court denied reimbursement for medical expenses because there were no supporting documents and the illness arose before the investigation began. My question is: if my health deteriorates or additional expenses arise during unlawful prosecution, under what conditions can I obtain compensation specifically for material damage? What needs to be presented to the court to prove this, and is there a chance to receive such compensation if there is a direct link between the investigation and the deterioration of health?
