Both pharmacological and non-pharmacological interventions are available. For pharmacological interventions, please refer to section 07.05. For non-pharmacological interventions, rehabilitation day hospitals and NGO-operated community care service units provide a wide range of interventions, including but not limited to, cognitive training, occupational therapy, reality orientation therapy, reminiscence therapy, validation therapy, multisensory stimulation intervention, physical exercise programme, cognitive stimulation therapy, music therapy, aromatherapy, carer educational programme, and carer stress-reduction interventions. Yet, owing to the diversity of the practices of service providers, there is no comprehensive statistics on the provision of different types of non-pharmacological interventions available.
