The prescribe and forget culture is the most damaging.
That all does sound like Good newsThe committee looked at the prescription of antipsychotics to care home residents.
It concluded that around 70% of prescriptions are inappropriate, equating to around 105,000 people with dementia.
People also often stayed on the medication for far longer than was necessary, it concluded.
The MPs propose a five-point plan to address the issue for inclusion in the government's National Dementia Strategy, due to be published later this year.
* Specialist dementia training for all care home staff
* Families to be involved in all decisions about giving the drugs
* More support for care home staff from GPs, psychiatrists and psychiatric nurses
* Compulsory patient reviews every 12 weeks
* A cost-effectiveness review by NICE, the National Institute of Health and Clinical Excellence and a national audit by the Care Quality Commission, which supervises care homes
Jeremy Wright MP, chairman of the group, said: "The government must end this needless abuse and make the five-point-plan a key element of the strategy.
"Safeguards must be put in place to ensure antipsychotics are always a last resort."
He added: "We need to include families in decisions, give people with dementia regular reviews and equip care staff with specialist training.
