Depressed people who display "risky behaviour", agitation and impulsivity are at least 50% more likely to attempt suicide, a study has found.
The study said effective prevention measures were "urgently needed".
The ECNP study evaluated 2,811 patients suffering from depression, of whom 628 had previously attempted suicide.
Researchers "looked especially at the characteristics and behaviours of those who had attempted suicide", and found that "certain patterns recur" before attempts.
They said the risk of an attempt was "at least 50% higher" if a depressed patient displayed:
- "risky behaviour" such as reckless driving or promiscuous behaviour
- "psychomotor agitation" such as pacing around rooms or wringing their hands
- impulsivity - defined by the researchers as acting with "little or no forethought, reflection, or consideration of the consequences"
Dr Dina Popovic, one of the report's authors, added: "We found that 'depressive mixed states' often preceded suicide attempts.
"A depressive mixed state is where a patient is depressed, but also has symptoms of 'excitation', or mania."
