A new LTE protocol named LTE Direct is a device-to-device technology enabling the discovery of thousands of devices in the proximity of approximately 500 meters.  Pioneered by Qualcomm , the company has been leading the standardization of this new technology along with other 3GPP participants. LTE Direct offers several advantages over existing proximity solutions including but not limited to Wi-Fi or Bluetooth . One of the most popular use cases for this technology was developed by a New York City based company called Compass. The core feature of proximal discovery among devices included a targeted discount voucher to a nearby device which matched specific interests.  The Compass use case was featured at global conferences and events such as CES 2015, MWC 2015, and said to be extended to many other scenarios including film festivals, theme parks and sporting events. It is claimed [ by whom? ] that the protocol offers less battery drainage and extended range when compared to other proximity solutions.
An assessment for an underlying cause of behavior is needed before prescribing antipsychotic medication for symptoms of dementia .  Antipsychotics in old age dementia showed a modest benefit compared to placebo in managing aggression or psychosis, but this is combined with a fairly large increase in serious adverse events. Thus, antipsychotics should not be used routinely to treat dementia with aggression or psychosis, but may be an option in a few cases where there is severe distress or risk of physical harm to others.  Psychosocial interventions may reduce the need for antipsychotics.
