He is investigating the role of small vessel cerebrovascular disease in causing executive deficits using behavioral and neuroimaging techniques. In addition, a series of projects have demonstrated the relationship between executive problems and poor outcomes such as increased caregiver burden, failure in activities of daily living, and apathy. He is also involved in studies measuring executive functioning in obsessive-compulsive disorder OCD and depression in patients undergoing deep brain stimulation treatment.
Abstract Clinical signs of upper motor neuron UMN involvement are an important component in supporting the diagnosis of amyotrophic lateral sclerosis ALSbut are often not easily appreciated in a limb that is concurrently affected by muscle wasting and lower motor neuron degeneration, particularly in the early symptomatic stages of ALS.
Whilst recent criteria have been proposed to facilitate improved detection of lower motor neuron impairment through electrophysiological features that have improved diagnostic sensitivity, assessment of upper motor neuron involvement remains essentially clinical. As a result, there is often a significant diagnostic delay that in turn may impact institution of disease-modifying therapy and access to other optimal patient management.
Biomarkers of pathological UMN involvement are also required to ensure patients with suspected ALS have timely access to appropriate therapeutic trials.
The present review provides an analysis of current and recently developed assessment techniques, including novel imaging and electrophysiological approaches used to study corticomotoneuronal pathology in ALS.

If the back part of the frontal lobe (which controls voluntary movements) is damaged, weakness or paralysis can result.
Because each side of the brain controls movement of the opposite side of the body, damage to the left hemisphere causes weakness on the right side of the body, and vice versa. Assessment of Aggressive and Agitated Behaviour What test is available to assess for agitated and aggressive behavior?
Agitated Behaviour Scale is designed to assess agitation in patients by those working with them. Attention Disorders / ADHD /ADD, Frontal Lobe Dysfunction.
Attention issues are currently affecting one in four individuals. More children, adolescents, and adults are becoming aware that they suffer from lack of attention whether diagnosed or not.
The frontal assessment battery (FAB), which includes simple tests of sequencing, behavioural inhibition, planning and frontal release signs, can be used as a screening test to elicit typical neurological and cognitive features.  Causes of Frontal lobe dysfunction. Head trauma. Consequently dysfunction of the frontal lobe can cause a wide range of symptoms (Kolb and Wishaw ) leading to relatively specific clinical dysfunction therefore a neuropsychological assessment is necessary to be carried out on the patient.
