The boundary between neurological and behavioural disorders often is not clear, and they often coexist. As a matter of fact, many neurological conditions lead to behavioural changes, which can be the only sign and the first sign complained by the owners. Sometimes it is not possible to reach a diagnosis based only on neurology or on behavioural medicine. Finally, some behavioural problems can facilitate the onset or worsening of neurological conditions. A synergy between neurology and behavioural medicine would be beneficial for both of them, in the diagnostic procedure and in the treatment. Veterinarians of such disciplines should collaborate as much as possible
