Living with Frontotemporal dementia with motor neuron disease

A type of frontotemporal dementia with symptoms of motor neuron disease, such as muscle wasting, starting in adulthood.

Understanding Frontotemporal dementia with motor neuron disease

Frontotemporal dementia with motor neuron disease (FTD-MND) is a type of frontotemporal lobar degeneration that also has features of motor neuron disease.

It starts gradually, between ages 38 and 78, with personality changes, uninhibited behavior, irritability, memory difficulties, and emotional changes. Speech problems can lead to loss of speech. It also includes muscle wasting like that seen in amyotrophic lateral sclerosis (ALS). The disease is progressive.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Personality and behavior changes
  • Memory and thinking problems
  • Hallucinations or depression
  • Slurred speech (dysarthria)
  • Muscle wasting
  • Trouble swallowing (dysphagia)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    The Association for Frontotemporal Degeneration may keep lists of experts for this condition.

InheritanceAutosomal Dominant

Changes in genes cause it. It is autosomal dominant, which means one changed copy of a gene is enough. GARD doesn't name the gene.
