health pr<strong>of</strong>essional about the halluc<strong>in</strong>ations <strong>of</strong> whom 59 (21% <strong>of</strong> those<br />

experienc<strong>in</strong>g halluc<strong>in</strong>ations) were given an explanation. Some explanations<br />

were <strong>in</strong>accurate or unhelpful e.g. psychological (N=1), bra<strong>in</strong> confusion (N=1),<br />

stress (N=2), noth<strong>in</strong>g to do with MD (N=1). In a study <strong>of</strong> 100 patients treated<br />

with PDT for predom<strong>in</strong>antly classic CNV, five (5%) described experienc<strong>in</strong>g<br />

structured halluc<strong>in</strong>ations follow<strong>in</strong>g treatment 110 .<br />

These studies <strong>in</strong>dicate that people may be reluctant to report halluc<strong>in</strong>ations<br />

for fear <strong>of</strong> be<strong>in</strong>g diagnosed with dementia or otherwise considered ‘crazy’ 76 109 .<br />

This concern alone may impact on QoL, severity <strong>of</strong> MD and halluc<strong>in</strong>ations<br />

notwithstand<strong>in</strong>g. Mitchell reported that halluc<strong>in</strong>ations were associated with<br />

poorer psychological well­be<strong>in</strong>g (W­BQ12 15 ) after controll<strong>in</strong>g for severity <strong>of</strong><br />

MD 75 . Scott reported that, even among people with relatively good VA, those<br />

experienc<strong>in</strong>g halluc<strong>in</strong>ations demonstrated higher levels <strong>of</strong> emotional distress<br />

(General Health Questionnaire [GHQ] 111 ) and decreased function (SIP 31 )<br />

compared with those without halluc<strong>in</strong>ations 109 . Health pr<strong>of</strong>essionals need to<br />

be aware <strong>of</strong> the likelihood <strong>of</strong> halluc<strong>in</strong>ations <strong>in</strong> MD and ask patients if they<br />

have experienced them. Reassurance about the benign nature <strong>of</strong> the<br />

phenomenon and its <strong>of</strong>ten limited duration would prevent much distress 112 113 .<br />

Cohen et al 110 suggested that all patients who undergo PDT should be told<br />

beforehand that halluc<strong>in</strong>ations are a possible side effect <strong>of</strong> treatment. Such<br />

pre­emptive education may be the best approach for all people diagnosed<br />

with MD 90 .<br />
