vision and hearing disorders can cause depression and anxiety which, if untreated, can lead to a premature death. this often occurs due to abuse of alcohol or drugs or, if seen in someone with a physical illness, the lack of communication between patient and healthcare providers. their quality of life can be vastly altered in regards to their social and physical capabilities and tolerances. often times in patients recovering from a physical or mental illness, it is difficult for them to feel safe enough/confident enough to express their feelings and symptoms.
