More people with intellectual disability are living independent lives. They can and do experiment with substances that the wider community try, such as alcohol and drugs (both legal and illicit). Unfortunately for some, they develop problems related to their use of these substances. Face‐to‐face, semi‐structured interviews were conducted with 13 professionals who work in Intellectual Disability Services and Alcohol &; Drug Services to discover their experiences of caring for people with intellectual disabilities who hazardously use substances. Although small numbers of people presented to these services, many more people with intellectual disabilities used Intellectual Disability Services for support, rather than their local Alcohol &; Drug Services. While the numbers may be relatively small, the challenges this client group pose are very perturbing in relation to their physical, emotional and social health. The professionals reported a lack of education in working with this doubly disadvantaged population. Moreover, policies were absent to guide staff to work collaboratively with this often‐ignored population. These findings are discussed in light of the innovative practices that are occurring in other parts of the UK regarding the recognition, assessment treatment and long‐term management of this population. Intellectual Disability Services and Alcohol &; Drug Services need to work more closely together if the needs of this population are to be effectively met.

Electrical induction of spikes in the hippocampus impairs recognition capacity and spatial memory in rats

In clinical studies, interictal EEG spikes (IS) have been associated with numerous neuropsychological abnormalities, ranging from transitory cognitive impairment to epileptic encephalopathies. Understanding the pathophysiological mechanisms of IS has been hampered by the lack of validated animal models. To mimic IS, a stimulating microelectrode was implanted in the ventral hippocampal commissure and a recording microelectrode in the CA1 region of the hippocampus of normal male rats. Spike patterns were induced using a series of electrical pulses 10-30 ms in duration with a frequency of 0.5-2Hz and a current of 0.2mA. The commissural stimulation-evoked population discharges in the hippocampus resembled naturally occurring IS in epileptic rats and, in no cases, resulted in behavioral seizures. For behavioral testing, the Morris water maze, radial arm maze, and object recognition tasks were used. Spikes were induced during sleep between the two sets of water maze trials; during the trials in the radial arm maze task; and prior to the sample phase and during the delay periods in the object recognition task. We demonstrated that rats that received spikes took longer to reach the escape platform in the second set of water maze trials; had significantly more reference errors and required more trials to complete the radial arm maze task; and had lower investigation ratios in the object recognition task. The results indicate that induction of spikes in the hippocampus results in impairment of spatial reference and nonspatial object recognition memory.
