Robertson (2002: 30) in his article on dental education, states that “our memories can be influenced by stress, drugs, and aging.” Hence, any one of these factors can affect the ability of students to learn new material and concepts. 
Research suggests that students with learning difficulties or health issues experience a high level of stress during their academic career. This higher level of stress can lead to increasing vulnerability to new or pre-existing health conditions. 
Recognizing that students learning difficulties may be a reflection of an underlying health situation may be the first step to assisting a student towards completing a successful clinical experience.
