Study population: The study will include patients with dementia of good cognitive level and necessarily have a caregiver. Patients may also live independently or with relatives or in a public or private care facility.

Brief summary: The main purpose of this study is primarily the translation and cross-cultural adaptation into Greek and then the investigation of validity and reliability in the Greek target population.

Detailed description: Two investigators will do the translation into Greek, then a third person independent of the first two will translate the scale backward, i.e. into English. Then, the three investigators will meet with another independent investigator who is familiar with the field of Greek translations of foreign language rating scales. Thus, the final translation and Greek version of the scale will be created. Then, the process of finding the participants will begin and the first assessment with the scale will be carried out initially. After two days will take place reassessment for the reliability of the measurement tool. In order to find the validity of the scale in the Greek population, in the first assessment will be used also Katz index for Basic Activities of Daily Living and the Lawton scale for Instrumental Activities of Daily Living.

Eligibility criteria: Inclusion Criteria:

* be diagnosed with any type of dementia
* have a carer
* have a good cognitive level

Exclusion Criteria:

* be end-stage or bedridden

Primary outcomes:
measure: Disability Assessment for Dementia and change from baseline
timeFrame: At baseline and after two days for checking the change and therefore the reliability. The score can range between 0 - 40, where 40 means complete independence in activities of daily living.
Secondary outcomes:
measure: Katz index for Basic Activities of Daily Living
timeFrame: At baseline. The score can range between 0 - 6, where 6 means complete independence in basic activities of daily living.
measure: Lawton scale for Instrumental Activities of Daily Living
timeFrame: At baseline.The score can range between 0 - 8 for women and 0 - 5 for men, where the highest scores means complete independence in basic activities of daily living.
