A variety of eye movement abnormalities, including supranuclear gaze palsy, have also been described in MND, 64 but these are rarely prominent. [pn.bmj.com]

Lower motor neuron disease causes weakness, loss of muscle ("atrophy") and muscle twitching ("fasciculations"). ALS may begin with abnormalities of upper or lower motor neurons. [neurology.emory.edu]

These persistent muscle twitches are generally not painful but can interfere with sleep. They are the result of the ongoing disruption of signals from the nerves to the muscles that occurs in ALS. [mda.org]

In upper motor neuron (UMN) disease, patients often experience resistance to movement and stiffness (muscle spasticity), over-reactive reflexes, and the Babinski sign, a specific reflex indicating damage to the neural pathways between the brain and spinal [newhealthadvisor.com]

Involvement of UMN results in stiffness of muscles (spasticity) and slowed movements. People may have only LMN or UMN signs early in the illness but typically develop a combination of the two as the disease progresses. [mndnsw.asn.au]

Oral antispastic agents are usually indicated in patients with diffuse or regional muscle spasticity rather than localized muscle spasticity. [cambridge.org]

Disease of the upper motor neurons causes stiffness of muscles (spasticity), muscle weakness and exaggerated tendon reflexes, such as knee jerks. [theconversation.com]

Again the level of the problem can generally be inferred from accompanying symptoms and signs, for example: Back pain and sciatica suggests a root problem Weakness of the biceps with absence of the biceps reflex, with upper motor neurone signs in the [ole.bris.ac.uk]

Female carriers may manifest more subtle symptoms such as cramps, back pain, or arthralgias. [clinicalgate.com]

Progressive sensorimotor deficits in the lower extremities with a history of memory loss or “attention deficit disorder” should also prompt testing for adrenomyeloneuropathy, as should a history of idiopathic childhood epilepsy or primary adrenal failure [clinicalgate.com]

No spasticity or hyperreflexia. [brainscape.com]

Examination reveals UMN signs in the legs (weakness, spasticity, pathological reflexes, hyperreflexia), although reflexes may also be brisk in the arms. [clinicalgate.com]

There are also rare progressive, autosomal recessive upper motor neuron degenerations (Infantile –Onset Ascending Hereditary Spastic Paralysis, Juvenile Primary Lateral Sclerosis, and Juvenile ALS) which begin during childhood and present with spasticity [neuropathology-web.org]

Concurrently, hyperreflexia of the jaw jerk and bilateral upper limb reflexes were normalized, and the bilateral Babinski reflexes became negative. Gaze paretic nystagmus and finger-to-nose incoordination were also improved. [bmcneurol.biomedcentral.com]

Patients may experience cognitive changes, for example trouble learning new things, or forgetting facts. They may also have problems with concentration and language. A small number of MND patients also develop dementia. [newhealthadvisor.com]
