Dual Sensory Loss, MCI, and a Sole Caregiver

With combined vision and hearing loss, the usable channel is touch plus a single, slowed auditory stream. That means:

• One instruction at a time, spoken at a moderate pace, without competing background sound. Do not talk while he is handling an object; he cannot watch your face and listen simultaneously.
• Tactile modeling with hand-under-hand demonstration, which lets him learn a routine without seeing it.
• Distributed practice and teach-back on a later day, not massed repetition in one session, because retention is the weak link.
• Reduce cognitive load - consistent object placement, one routine per visit, no new routine layered onto an unmastered one.

Before instruction, fix the sensory access:

1. Audiology referral. "They whistle" often means a poor fit or an unaddressed setting, not an unfixable device. Assistive listening devices and a remote microphone are alternatives if hearing aids remain refused. It is legitimate for him to decline; it is not legitimate to plan an auditory program without knowing what he can hear.
2. Safety alarms. Check the smoke detector - a standard alarm is useless to him. A bed shaker or strobe unit and a vibrating alert are appropriate, and his wife must be able to hear the standard alarm.
3. Fall risk, given the previous hip fracture and light perception only.

The MoCA is a screen, not a diagnosis, and it is confounded by vision and hearing loss in exactly this profile. Do not use the number to decide his capacity. Use functional performance:

• Can he learn and retain a safety-critical routine - medication identification, locating the phone, responding to an alarm - across at least two sessions with teach-back?
• Does he make a repeated error with money or medications that he cannot detect or correct?
• Is there a pattern suggesting exploitation, unusual withdrawals, or a new "helper"?

Accommodate when the barrier is sensory: give him large-print or tactile records, one bill at a time, and a routine he can perform. Overestimating looks like assigning independent bill-paying because he managed it for 50 years, then discovering unpaid notices weeks later. Underestimating looks like removing all financial involvement because of one screening score, which reinforces the burden narrative he just voiced.

The middle path is graduated involvement: he reviews a summary she prepares, or he handles one account with a verification step. Document his expressed wishes, and if capacity is genuinely in question, refer to his physician or a geriatric assessment rather than deciding it yourself. Financial and legal planning belongs with an elder-law attorney; your contribution is the functional evidence.

She is a co-client in the practical sense and a person with her own health limits, and treating her as a free therapy assistant is a plan that fails quietly.

• Assess caregiver burden directly. Ask about sleep, her own medical appointments, lifting, and what she has stopped doing for herself. Her cardiac condition plus caregiving plus night driving restrictions is a foreseeable crisis.
• Build the plan so it does not require her constant presence. Teach routines he can perform alone; schedule visits at times she can rest; consider a neighbor, a day program, or home health rather than assuming she will fill gaps.
• Address her transportation limit explicitly - daytime scheduling, delivery services for medications and groceries, and a written list of who to call.
• Offer respite and support referrals, and raise long-term planning (care coordination, advance planning) as a referral, not as your own advice.
• Do not make her the sole verifier of safety-critical tasks. If verification is needed for medications, an outside check - pharmacy blister packs, a visiting nurse - is more reliable than a spouse with her own condition.

Document both his and her stated goals. When they conflict, name the conflict, offer options, and let them choose.
